🗂 Part of event: Oregon Senate margin of victory →💡 What the odds say
The market puts this at about a 66% chance — likely.
No money — just record your call and see if you were right. Yes is at 66% right now.
The 66% odds for a 21-point Democratic victory in Oregon's 2026 Senate race reflect a safe-blue state baseline, but the margin is unusually high for a Senate race, suggesting the market is pricing in a national Democratic tailwind from Trump's declining approval and the Iran War, while ignoring potential local turnout dynamics that could narrow the gap.
📊 Base rate: In the last four Oregon Senate elections (2014, 2016, 2020, 2022), the Democratic margin of victory averaged 15.5 percentage points, with only the 2022 race exceeding 21 points (by 22.5 points), making the current 66% odds above the historical frequency of about 25%.
What's driving it
- • Trump's approval dropping to 43% in March 2026 (Newswire.com, Mar 30) and 57% of voters saying ICE and CBP have gone too far (USA Today, Feb 9) suggest a national environment favoring Democrats, which could boost Oregon turnout and margin.
- • The Iran War splitting support along partisan lines (Newswire.com, Mar 30) may energize Democratic base voters in Oregon, a state with strong anti-war sentiment, potentially increasing the margin.
- • No clear catalyst from recent Oregon-specific headlines; the most recent relevant national story is from July 11 about Black Democrats in the South (WSJ), which does not directly affect Oregon's Senate race.
The case for YES
- • Oregon is a reliably Democratic state; the party won the 2022 Senate race by 22.5 points, showing a 21-point margin is achievable even without a national wave.
- • Trump's approval rating is double digits higher than Democrats in Congress (Newsweek, Dec 22), but in a blue state like Oregon, that contrast could drive anti-Trump turnout, widening the Democratic margin.
- • The Iran War and economic discontent (Newswire.com, Mar 30) may disproportionately depress Republican turnout in Oregon, where the GOP is already a minority, making a large Democratic win more likely.
The case for NO
- • Historical margins in Oregon Senate races are often below 21 points; the 2014, 2016, and 2020 races all had Democratic wins by 10-17 points, suggesting a 21-point threshold is not the norm.
- • Trump's multiracial, working-class coalition is fraying (WSJ, Nov 7), but in Oregon, that could mean some Democratic-leaning voters shift to third-party or stay home, reducing the margin.
- • Replacing a Senate nominee is rare (NYT, Jul 9), but if the Democratic nominee faces a scandal or replacement, it could depress turnout or enthusiasm, narrowing the margin.
What to watch
- • Any Oregon-specific polling release in August-September 2026 showing the Democratic lead above or below 21 points would directly move odds toward the corresponding direction.
- • A major national event like a ceasefire in the Iran War or a significant economic improvement before November 2026 could reduce Democratic turnout advantage, pushing odds toward No.
- • If the Republican nominee in Oregon is a strong, well-funded candidate (e.g., a popular former governor or moderate), odds would likely shift toward No as the margin tightens.

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).
