🗂 Part of event: Oregon Senate margin of victory →💡 What the odds say
The market puts this at about a 48% chance — a coin toss.
No money — just record your call and see if you were right. Yes is at 48% right now.
The near-even odds reflect a tug-of-war between Oregon's deep-blue lean and the possibility that a national Republican wave or a uniquely weak Democratic nominee could compress the margin below 25 points, making this less a referendum on Oregon than on national political winds.
📊 Base rate: In the last six U.S. Senate elections in Oregon (2008–2022), Democrats have won by an average margin of about 21 percentage points, with only two of those races exceeding 25 points (2008: 31 points; 2022: 27 points), giving a historical prior of roughly 33% for a 25+ point margin.
What's driving it
- • National polling showing Trump approval at 57% disapproval (USA Today, Feb 9) and double-digit approval advantage over congressional Democrats (Newsweek, Dec 22) suggests a favorable GOP environment that could boost Republican turnout and narrow the Oregon margin.
- • A Washington Post analysis (Jan 16) identified Oregon as a state where Democrats see a narrow path to retaking the Senate, implying the race is competitive enough that a blowout margin is not guaranteed.
- • Signs of fraying in the multiracial, working-class coalition that helped Democrats in recent cycles (WSJ, Nov 7) could reduce Democratic vote share in Oregon, making a 25-point win less likely.
- • No clear catalyst from recent Oregon-specific headlines; the cited articles focus on national trends and other states, leaving local dynamics as a key unknown.
The case for YES
- • Oregon has voted Democratic in every presidential election since 1988 and in every Senate race since 1996, providing a structural floor that makes a 25-point margin plausible in a neutral or pro-Democratic year.
- • The 2022 Senate race saw Democrat Ron Wyden win by 27 points, showing that a 25+ point margin is achievable even in a midterm with a Democratic president, suggesting the bar is not historically out of reach.
- • If national sentiment shifts against the GOP due to overreach by ICE and CBP (USA Today, Feb 9), Democratic turnout could surge in a blue state like Oregon, widening the margin.
The case for NO
- • National headwinds from Trump's approval rating being double digits higher than congressional Democrats (Newsweek, Dec 22) could depress Democratic turnout and energize Republicans, compressing the margin below 25 points.
- • The Washington Post (Jan 16) highlighted Oregon as a state where Democrats face a narrow path, implying the race is tighter than a blowout, with factors like candidate quality or local issues reducing the margin.
- • Historical base rate shows only 2 of the last 6 Oregon Senate races exceeded 25 points, making the current 48% odds arguably high relative to the 33% prior, suggesting a reversion to a narrower win is more likely.
What to watch
- • Release of Oregon-specific polling in late summer 2026 (e.g., from a reputable firm like SurveyUSA or DHM Research) would directly test the margin; a poll showing a lead under 20 points would push odds toward No, while a lead over 30 points would push toward Yes.
- • The outcome of the Democratic primary (likely May 2026) and the identity of the nominee could shift odds; a polarizing or scandal-tainted nominee would lower the expected margin (toward No), while a popular incumbent or consensus pick would raise it (toward Yes).
- • National events like a major economic downturn or a foreign policy crisis in the fall of 2026 could alter the national mood; a crisis benefiting the incumbent party would boost Democratic turnout and widen the margin (toward Yes), while one benefiting the opposition would narrow it (toward No).

Democratic Presidential Nominee 2028
The field is virtually nonexistent: only two candidates register at 1% each, and no one has broken 5%, making this the most open Democratic nomination race in modern history. The single biggest recent shift is the DNC's decision to put South Carolina first in the 2028 primary calendar (Axios, Jul 25), which could reshape candidate strategies and favor a different type of contender.

Next Prime Minister To Replace Keir Starmer
The field is highly concentrated, with Andy Burnham absorbing nearly all of the probability after Starmer’s resignation and a key endorsement, pushing the top three candidates' combined odds to an unsustainable 110% that signals liquidity imbalances or heavy speculative positioning. The biggest recent shift is Burnham’s surge to 99% following the ‘Starmer Announces Resignation; Burnham Wins Key Endorsement’ headline (The New York Times, Jun 23).
