Amid new uncertainty in the Middle East, President Donald Trump’s odds get just a bit better this week. The Democrats, meanwhile, have returned to a clearly two-tiered race — and two popular names aren’t at the top.

What are the Odds Donald Trump Wins Re-Election?

Trump’s odds improved slightly this week to 4/5 (-125). While next week’s news cycle will almost certainly be dominated by fallout from the decision to strike and kill elite Iranian military leader Qassem Soleimani, it hasn’t been reflected in Trump’s odds. His approval rating is still underwater but not unwinnable. In general election polls, he’s ahead of everyone but former Vice President Joe Biden.

Trump campaigned on non-intervention in the Middle East in 2016, and surrogates have used the lack of new theaters of operation as a selling point for a second term, which might undercut the typical approval ratings boost a wartime president gets. How the next week unfolds will be critical for his re-election campaign.

Joe Biden 2020 Odds

Biden shortened to 5/1 (+500) this week, one of his best positions of the election cycle. He has opened a double-digit lead nationally. There’s some concern in his fundraising numbers, possibly suggesting a dip in enthusiasm, but the quarterly haul was plenty and until we see other problems, it’s sweating the small stuff in comparison to his poll numbers.

Bernie Sanders 2020 Odds

Sen. Bernie Sanders, like Trump and Biden, shortens as well, to 6/1 (+600). He continues to post primary-leading fundraising numbers and his late-fall/early winter comeback is, like Biden, still the dominant narrative without new polling.

Elizabeth Warren 2020 Odds

Sen. Elizabeth Warren drops a bit to 14/1 (+1400). Her national polls remain a strong third, but the lack of new state polling makes it hard for her to contradict the narrative that she has fallen off in the early states, and her fundraising numbers lag well behind the top three men.

She easily qualified for the January debate, after which there will likely be a host of new polling, which might make the debate a make-or-break moment for her. If she cedes the progressive ground in both early states, that would likely create an insurmountable hill for her.

Michael Bloomberg 2020 Odds

Michael Bloomberg drifts to 20/1 (+2000). He’s still looking to turn attention into votes; with a week left in this debate’s qualification period, he has zero qualifying polls by either state or national criteria. In a race where he entered late and still isn’t a big name outside New York, it’s tough to see him growing a campaign without the benefit of debate-level exposure, even with his huge national ad budget.

Pete Buttigieg 2020 Odds

Buttigieg, now the former mayor of South Bend, Indiana, has the longest drift of any candidate this week, tying with Bloomberg for fifth at 20/1 (+2000). Unlike Sanders and Biden, Buttigieg isn’t helped by the dearth of new polls.

Though he has put in strong work in New Hampshire and Iowa, Buttigieg is still looking for a national polling breakout. He’s still averaging big enough numbers to qualify nationally and has qualified for the debate via state polling.

Hillary Clinton 2020 Odds

Former Sen. Hillary Clinton once again clocks in at 25/1 (+2500). After repeatedly denying she’d run in 2020, Clinton has taken the extra step of taking a job out of the country, becoming chancellor of Queen’s University in Belfast. Just like last week, the oddsmakers likely feel little need to update her odds given that there’s no more reason to take her seriously as a 2020 candidate.

Andrew Yang 2020 Odds

Andrew Yang remains at 33/1 (+3300) this week, a number he has held for a while. The last candidate to qualify for and only candidate of color in the December debate, he’s struggling to qualify for the January one with a little less than one week left.

It’s a tough time to need polls, though. While the DNC allows candidates to meet either national or state polling criteria this time around, organizations involved in state polling are often less active for the holidays. It’ll be another round of late nights for his campaign, and a very bad sign if he doesn’t make the cut.

Amy Klobuchar 2020 Odds

As with multiple debates before, Sen. Amy Klobuchar received a bounce after a well-received debate performance. But her drift back to 66/1 (+6600) shows that her momentum does not translate to polls. She qualified for the January debate, which could mean another promising swing upward, but unless she scores big there she will have a hard time breaking out of the pack and into the race’s top tier.

Mike Pence 2020 Odds

Vice President Mike Pence drifts to 80/1 (+8000) this week. It might be too late to mount a primary campaign to replace Trump (something Pence does not seem willing to do anyway). Those chances likely become even more remote as the traditionally hawkish Republican Party further coalesces around Trump through the Iran crisis.

Candidates with Longer than 100/1 Odds

Julian Castro, who had been at 150/1 (+15000) ended his presidential bid this week. He had missed two consecutive debates and had narrowly avoided debt-induced fundraising deadlines multiple times. Fellow long shot Cory Booker (150/1) has begun to court Castro’s donors.

Next Winning Party Odds

For the first time, the GOP has moved into the favorite role. The Republican Party is 41/50 (-122) and Democrats drifted to 10/11 (-110) this week. Any other party remains a 50/1 (+5000) shot.
