As the 2020 presidential election draws closer, certain Democratic hopefuls are beginning to separate themselves from the pack.

While a lot can happen to the candidates within the next year, BetOnline has odds on the matchups between President Donald Trump and the eventual Democratic nominee.

The site is accepting action on five general election matchups, each involving Trump and a Democrat. Trump’s opponents include former Vice President Joe Biden (+300 odds of winning the Democratic nomination), South Bend, Indiana Mayor Pete Buttigieg (+1400), Sen. Kamala Harris (+650), Sen. Elizabeth Warren (+250), and entrepreneur Andrew Yang (+1200).

Trump’s prop bet opponents make up five of the top six Democrat candidates, based on BetOnline’s Democratic nomination odds. Sen. Bernie Sanders, the Democrat with the third-best odds at +600, is not an option for the Trump matchup bets.

To be clear, the candidates must first win the Democratic nomination for the “Yes” bets to be winnable. If the candidate does not become the Democratic nominee or they lose in the general election, the “No” bet wins.

Nevertheless, what are the chances a candidate can get the nomination and then defeat Trump in the general election?

The leader in nearly every political poll, Biden has the best odds to defeat Trump in the 2020 election, compared to the other candidates’ chances. Oddsmakers give Biden +400 odds to defeat Trump, but -500 to lose the election as the Democratic nominee. From there, a matchup victory for the Democrats grows thinner.

Warren, the candidate with the best chances to win the Democratic nomination, has the second-best odds to defeat Trump if the two meet in 2020. At +800 odds, Warren is a longshot at defeating Trump, especially when her loss is favored at -1250.

After Warren, Harris has the next best odds of defeating Trump as the Democratic nominee. The former party favorite has slipped in the odds since the second debate in July. Her odds of earning the Democratic nomination but losing to Trump are -2500. Her odds of beating Trump are only +1400.

Mayor Pete has a decent chance of winning the Democratic nomination at +1400 according to BetOnline, but they don’t give him great odds of turning the nomination into a successful presidential run. Buttigieg has +2000 odds of beating Trump but -5000 odds of losing to the incumbent.

Like Buttigieg, Yang has +2000 odds to defeat Trump and -5000 to lose to him. However, Yang is not a career politician like most other Democrat candidates. During his 2016 presidential run, one of Trump’s biggest appeals was that he was a businessman, not a politician. Yang has the same background, which could help him if he’s the Democrat’s pick.
