President Donald Trump has a decent shot of securing the White House for a second term in the 2020 presidential election, according to the world’s largest online sportsbooks. However, most people betting on the new president think he’ll be impeached or removed from office before his reelection campaign ever comes to fruition.

BetOnline.ag, one of the leading betting sites where users can roll the dice on political candidates internationally, has been tracking Trump’s Vegas odds since his shocking electoral upset victory in 2016.

Though 86 percent of those placing bets on 2020 have chosen Trump as the most likely presidential election winner, his odds have been plummeting for months. There remained just a 40 percent chance Trump will still be in office by the time voters flock to the poll in the next presidential election.

Meanwhile, bettors have been throwing money behind several of Trump’s potential contenders, with arguably safer choices including politicians like Vice President Mike Pence, Sen. Elizabeth Warren, D-Mass., Sen. Cory Booker, D-N.J., and Rep. Julian Castro, D-Tex., and some arguably longshots like former first lady Michelle Obama and rapper Kanye West, who has previously said he’d run in 2020 before Trump took the Oval Office last year.

Former Secretary of State Hillary Clinton was also being betted on to defeat Trump during his reelection campaign, despite her defeat in 2016 possibly marking her last run for office.

Just like his plummeting betting odds for reelection, Trump has also suffered declining approval ratings for the majority of his short presidency, dipping to just 38 percent total support nationwide in the most recent Gallup tracking polls from March 27 to April 2. New presidents typically receive a "honeymoon period," in which their popularity among the public remains high over the course of the first 100 days before typically lowering throughout the rest of their tenures in office.
