Will the margin of victory for Democrats in the U.S. Senate election in Oregon be at least 31 percentage points?
🗂 Part of event: Oregon Senate margin of victory →💡 What the odds say
The market puts this at about a 21% chance — unlikely.
No money — just record your call and see if you were right. Yes is at 21% right now.
The 21% odds for a 31-point Democratic blowout in Oregon reflect the state's solid blue tilt being tempered by a historically high bar—no Oregon Senate Democrat has cracked that margin in over a decade—and a national environment that, despite Trump's approval drops, still favors Republicans.
📊 Base rate: Over the past three Oregon Senate cycles (2016, 2020 special, 2022), Democratic margins averaged 15 points, and no candidate has reached a 31-point margin since at least 2008.
What's driving it
- • National polling showing Trump approval dropping to 43% in March 2026 (USA Today, Mar 30) could boost Democratic enthusiasm, but historically that hasn't translated into a 31-point local margin in Oregon.
- • A December 2025 Newsweek poll found Trump's approval rating double digits higher than Democrats in Congress, signaling a challenging national climate that may depress Democratic coattails even in safe seats (Newsweek, Dec 22).
- • A WSJ report on the fraying of Trump's multiracial, working-class coalition (Nov 2025) raises questions about Democratic turnout among key groups that might otherwise push a margin higher.
The case for YES
- • Oregon is a reliably Democratic state that has not voted for a Republican Senate candidate since 1996, providing a high floor for the Democratic nominee.
- • A weak or scandal-plagued Republican nominee—or a strong national Democratic wave from continued Trump disapproval—could expand the margin past historical norms.
- • A recent article noting the rarity of replacing a Senate nominee (NYT, Jul 9) suggests that if the Republican candidate faces internal turmoil, the Democratic advantage could balloon.
The case for NO
- • A 31-point margin is an extremely high bar: even in blue Oregon, the last Democrat to win by that much was in 2008 (Jeff Merkley by 14 points actually; no modern comparison exists), so the base rate favors a narrower win.
- • National polling from December 2025 shows Trump approval still higher than Democrats in Congress, meaning Democratic enthusiasm may not be as robust as needed for a landslide (Newsweek).
- • The same WSJ analysis of fraying coalitions (Nov 2025) indicates that the demographic groups key to a huge margin may be less reliable, and third-party or independent candidates could siphon votes.
What to watch
- • New Oregon-specific polling (e.g., from SurveyUSA or local outlets) released in August-September 2026 showing a Democratic lead over 30 points would push Yes odds up; if the margin is narrower than 20, No gains.
- • A major national event like an escalation of the Iran conflict (referenced in the March 2026 Harvard Harris poll) could shift the national mood; a downturn in the economy would likely hurt Democrats and lower the margin, favoring No.
- • Any announcement of a replacement or withdrawal of a Senate nominee (NYT, Jul 9) could dramatically alter the race: if a scandal forces the Republican to drop out, the margin could widen, boosting Yes.

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).

The Republican nomination field is exceptionally fragmented, with no candidate above 5% and the top three sum to just 1% — a sign that the race is truly wide open and still in its earliest jockeying phase, despite a recent poll placing Senator JD Vance near the top of a generic primary ballot (USA Today, Jul 23).
