Susan Collins faces her toughest reelection yet against Troy Jackson after a chaotic Democratic candidate swap. Here’s why Maine is a genuine Senate toss-up.

Republican Sen. Susan Collins faces Democrat Troy Jackson, a former Maine Senate president, in a toss-up 2026 general election after Democrats’ original nominee, Graham Platner, was replaced through a special party nomination process. Recent polling shows Jackson with a slight edge.

For a senator who has survived six consecutive campaigns and just cast her 10,000th consecutive Senate vote, Susan Collins now faces what independent analysts are calling a genuine toss-up race — one of the clearest tests of whether Republicans can hold their Senate majority in November.

A Late, Chaotic Democratic Swap

The road to Collins’ current opponent was unusually turbulent. Maine’s Democratic field originally centered on a three-way primary between Gov. Janet Mills, oyster farmer and combat veteran Graham Platner, and former Maryland government official David Costello. Mills dropped out in April, leaving Platner as the grassroots-backed front-runner heading into the June 9 primary — a candidate whose anti-establishment profile and matched fundraising against Collins had national Democrats excited about their odds.

But Platner’s candidacy collapsed amid revelations that included past social media posts and a tattoo resembling a Nazi symbol. With the general election bearing down, the Maine Democratic Party activated an emergency special nomination process — built around county-level delegate meetings rather than a snap primary — to replace him. On July 25, that process produced Troy Jackson, a former Maine Senate president, as the party’s new standard-bearer with roughly 100 days left until Election Day.

Why the Race Is Genuinely Competitive

Despite the compressed timeline, early data suggests Jackson is not merely a placeholder candidate. A Pine Tree Poll conducted by the University of New Hampshire Survey Center showed Jackson with a three-point edge over Collins among likely general-election voters, and Fox News’ inaugural 2026 Power Rankings classify the race as a toss-up — one of roughly a dozen Senate contests that will determine which party controls the chamber.

Collins’ vulnerabilities are structural as much as political. Maine backed the Democratic presidential ticket by seven points in 2024, meaning Collins has long relied on ticket-splitting voters to survive in a state that leans against her party nationally. Democrats are also targeting her more directly than in past cycles, criticizing her comment that she doesn’t regret her 2018 vote to confirm Justice Brett Kavanaugh despite his later vote to overturn Roe v. Wade, and her continued support for Immigration and Customs Enforcement funding following a fatal shooting in Maine involving ICE agents earlier this month.

Collins, who chairs the powerful Senate Appropriations Committee, is leaning on 28 years of relationship-building with industries dependent on federal spending, along with a substantial outside-money advantage. In her campaign launch, Collins argued that “my experience, seniority and independence matter,” while Democrats have countered that “seniority without a backbone is just tenure.”

What It Means for Senate Control

Maine is one of two Senate seats Democrats are defending — or, in Collins’ case, one Republicans are defending — in a state won by the opposing party’s presidential nominee in 2024, making it a marquee Senate battleground alongside Georgia, North Carolina, and Alaska. Democrats need to net four seats nationally to reclaim the majority, and unseating Collins is widely viewed as central to that math given how few genuinely competitive Republican-held seats exist on the 2026 map.

The compressed Jackson campaign timeline is itself a variable worth watching: Collins has now defeated multiple well-funded Democratic challengers over her career, and whether Jackson can build statewide name recognition and a comparable small-dollar fundraising operation in roughly 14 weeks will likely determine whether Maine actually flips or simply stays close.

Most headlines on Russia’s economy in July 2026 focus on the latest sanctions package or oil price cap negotiation. The more important story is structural: the model Russia has used to fund its war for four years is showing real signs of running out of road.

The core finding

A research brief from the Center for Strategic and International Studies (CSIS) argues Putin is pushing Russia toward an “economic, political, and military abyss,” according to Fortune. While Russia’s economy remains large — roughly $2.6 trillion — growth is slowing and shrinking on a quarterly basis, with 2026 growth projected at just 0.4%, worse than 2025’s 1% growth, which itself narrowly avoided recession.

Analysts describe Russia’s approach as a form of “military Keynesianism” — the state investing heavily in militarizing the economy while extending financial support to households affected by the war. But per Fortune’s reporting, “after more than four years of war, that well is running dry.” Russia’s fiscal reserves are dwindling, and 71% of the country’s gold reserves have been liquidated to sustain spending.

The number that matters most: oil and gas budget share

The most underreported data point here: the share of oil and gas receipts in Russia’s federal budget revenue fell to just 23% in 2025 — the lowest share in two decades — according to the Oxford Institute for Energy Studies, cited by Fortune. To compensate, Russia has turned to expansive taxation, including raising VAT from 20% to 22% — a move that has proven unpopular domestically.

This matters because Russia’s economy has historically been described, correctly, as fossil-fuel dependent — with oil and gas taxation making up 44% of federal revenues in the decade before the Ukraine invasion, and still around 24.5% over the first three quarters of 2025, according to a Brookings Institution analysis. A further slide to 23% signals the sanctions and diversification pressure are compounding, even as Russia continues finding workarounds through its “shadow fleet.”

The Iran-war reprieve was temporary — and it’s over

The Iran war offered Russia a brief lifeline: Brent crude surged more than 55% at its peak, nearing $120 a barrel, after President Trump eased some sanctions on Russian oil, per Fortune. But that chaos also undermined Russia’s own long-term energy and infrastructure projects in the Middle East — two Russian-linked power plants in Iran were put on hold, along with oil and gas exploration and plans to link Russia to India via Iran through new transit routes. Since then, oil prices have normalized as demand softened and the Strait of Hormuz reopened, removing that temporary cushion.

The sanctions escalation now in motion

The pressure is intensifying on multiple fronts simultaneously. US senators unveiled a sweeping bipartisan Russia sanctions bill in mid-July, which would impose mandatory sanctions on Russian political and military leaders including President Putin, and up to a 100% tariff on the top five countries — including China and India — that purchase Russian crude oil and natural gas, according to CNN. Separately, the EU has been racing to avoid an automatic upward revision of its Russian oil price cap, which would otherwise jump from $44.10 to roughly $58 per barrel if a new sanctions package wasn’t agreed by July 15, per Euronews.

Analysis from the Center for European Policy Analysis notes the outcome depends heavily on whether India and China accept the risk of secondary sanctions: “If China stands firm, Moscow’s dependence on Beijing deepens,” per CEPA. If Russian seaborne oil exports were to fall to near-zero, the budget would lose roughly a quarter of its revenue — an extreme but non-trivial scenario given the pace of legislative and diplomatic pressure building in July 2026.

Why this matters beyond Russia

For countries positioned between Western sanctions regimes and continued Russian energy purchases — including India, and by extension trade partners like Pakistan whose remittance and trade flows intersect with Gulf and South Asian energy markets — the trajectory of Russia’s budget dependency and the secondary-sanctions risk attached to its buyers is a live variable, not a settled one. A further deterioration in Russia’s oil-and-gas revenue share would likely accelerate Moscow’s reliance on China specifically, reshaping regional energy-trade alignments well beyond the Russia-Ukraine conflict itself.

FAQ

What percentage of Russia’s federal budget comes from oil and gas? 23% in 2025 — the lowest share in two decades, according to the Oxford Institute for Energy Studies.

What is Russia’s projected GDP growth for 2026? 0.4%, according to CSIS research cited by Fortune — down from 1% growth in 2025.

What is “military Keynesianism” in the context of Russia’s economy? A term analysts use to describe Russia’s strategy of heavy state investment in militarizing the economy alongside financial support for war-affected households, functioning as a form of stimulus that is now showing signs of fiscal strain.

Russia‘s two largest, US-sanctioned oil producers have clawed back control of the majority of the country’s crude export trade, restoring their combined share to 57% in the first half of May 2026 after a sharp decline earlier in the year — a recovery that underscores the limits of Western sanctions enforcement even as the Middle East conflict reshapes global energy flows in Moscow’s favor.

According to the Kyiv School of Economics Institute‘s Russian Oil Tracker, sanctioned producers Rosneft, Lukoil, Gazpromneft, and Surgutneftegaz had seen their combined export share collapse to just 4-8% in the January-to-March period, only to rebound sharply as sanctioned “shadow fleet” tankers and previously idle vessels returned to commercial service, according to KSE Institute’s May 2026 tracker. The reversal illustrates a pattern that has recurred throughout the sanctions era: enforcement gaps open, capital and logistics networks adapt, and market share flows back toward sanctioned entities within a matter of months.

The Shadow Fleet’s Growing Dominance

The scale of Russia’s reliance on unconventional shipping infrastructure has reached a new high. KSE Institute estimates that 192 shadow fleet tankers carrying crude and refined products left Russian ports or engaged in ship-to-ship transfers in April 2026 alone, with 92% of those vessels older than 15 years — aging tonnage increasingly steered toward sanctions-evasion routes as newer, compliant vessels avoid the reputational and insurance risk of handling Russian crude.

The share of Russian seaborne oil transported by explicitly sanctioned tankers rose from 15% in July 2025 to 31% by April 2026, according to KSE data, while the corresponding share carried specifically by US-designated vessels reached 26% over the same window — driven, according to the tracker, by previously idle tankers returning to active commercial rotation. As of May 21, six major sanctioning jurisdictions — the US, UK, EU, Australia, Canada, and New Zealand — had jointly designated 651 unique oil tankers, yet the fleet supporting Russian exports has continued to expand around those designations rather than shrink beneath them.

Separately, monthly analysis from the Centre for Research on Energy and Clean Air (CREA) found that in April 2026, over half — 54% — of Russia’s seaborne oil moved via sanctioned shadow tankers, up sharply from 48% in March, with sanctioned vessels responsible for the highest share of Russian fossil fuel exports on record, according to CREA’s April 2026 monthly tracker.

Revenue Keeps Climbing Despite the Sanctions Architecture

The financial consequence of this logistics resilience is a fossil fuel export revenue stream that has continued growing even as enforcement pressure has, on paper, intensified. Russia’s fossil fuel export revenues rose 2% month-on-month to €726 million per day in May 2026, according to CREA’s most recent analysis, despite export volumes remaining broadly flat. Crude oil export revenues specifically grew 1% to €362 million per day, with volumes up 8% — evidence that Russia is finding new efficiencies in its export logistics even as the headline sanctions regime tightens.

KSE Institute’s revenue modeling, updated in light of the Middle East conflict, now projects that Russia’s total oil revenue could climb from $158 billion in 2025 to $208 billion in 2026 under a base-case scenario assuming current price caps and a conflict lasting up to three months. Under an adverse scenario involving weak sanctions enforcement, that figure could reach $214 billion — meaning even the coalition’s most pessimistic enforcement scenario still implies rising, not falling, Russian oil revenue for the year.

Pricing dynamics tell a related story. Russia’s benchmark Urals crude rose 19% month-on-month in April 2026 to $112.30 per barrel — more than double the $44.10 EU and UK price cap that took effect on February 1, 2026 — before easing 12% in May to $82.02 per barrel, still nearly double the cap, according to CREA’s tracking data. The price cap, designed explicitly to constrain Russian per-barrel revenue while keeping global oil supply flowing, has functioned as a floor for insurance and freight compliance rather than an effective revenue ceiling during periods of tight global supply.

Third-Country Refineries Remain a Persistent Loophole

Refineries in India, Türkiye, Brunei, and Georgia running on Russian crude exported €641 million worth of oil products to sanctioning countries in May 2026 alone, according to CREA, including shipments to the EU, Australia, the US, and New Zealand — jurisdictions that have formally banned direct imports of Russian crude but continue receiving refined products derived from that same crude once it has passed through a third-country refinery. Georgia’s Kulevi refinery has run entirely on Russian crude for months without receiving a single shipment of non-Russian oil, despite its operating company publicly stating an intent to diversify — and despite narrowly avoiding inclusion on the EU’s sanctions list in March.

The EU closed one version of this loophole through its 18th sanctions package in January 2026, banning oil products refined from Russian crude in third countries from entering the bloc, according to analysis from the Center for European Policy Analysis (CEPA). Yet the persistence of flows through Kulevi and similar facilities illustrates how quickly new evasion routes emerge once established ones are formally closed — a pattern sanctions researchers describe as a continuous cat-and-mouse dynamic rather than a one-time enforcement fix.

What the Data Means for the Broader Sanctions Debate

Since Russia’s full-scale invasion of Ukraine, sanctions imposed by the UK, US, and EU are estimated to have denied Russia access to more than $450 billion, according to CEPA’s analysis — a substantial figure that nonetheless coexists with the reality that Russia’s oil exports since February 2022 have generated more than $800 billion in revenue through April 2026, according to CREA data cited in the same CEPA report. Those two figures, both accurate, capture the fundamental tension at the heart of Western sanctions policy: meaningful financial damage has been inflicted, but Russia’s core oil revenue engine has continued operating at a scale sufficient to sustain its war economy.

For markets and policymakers tracking global oil supply through the remainder of 2026, the practical implication is that Russian barrels — whether transported via shadow fleet, laundered through third-country refineries, or shipped directly by re-empowered sanctioned majors — remain a structurally embedded part of global crude supply, with enforcement gaps proving durable enough that even renewed sanctions packages have thus far failed to meaningfully compress Russia’s oil-derived war financing.
