2020 Presidential Election Odds Updated: Bernie Sanders Announces, but Can Donald Trump Be Defeated?

Vermont Senator Bernie Sanders announced on Tuesday that he'll give it another go in 2020, running for president again after an upstart 2016 bid in which he lost out to eventual Democratic nominee Hillary Clinton.

But while Sanders begins his second campaign with the kind of name recognition he lacked the first time around, he again faces an uphill task to take the White House, according to oddsmakers.

Meanwhile, he didn't waste time going after President Donald Trump in an interview with Vermont Public Radio that aired on Tuesday.

"I think the current occupant of the White House is an embarrassment to our country," Sanders said. "I think he is a pathological liar.… I also think he is a racist, a sexist, a homophobe, a xenophobe, somebody who is gaining cheap political points by trying to pick on minorities, often undocumented immigrants."

Reports say Sanders, 77, has already received donations from all 50 states. But, according to oddsmakers, it's more likely that Trump will be president after the November 2020 vote.

BetOnline had Trump as the clear favorite to win in 2020, at 3-2 odds. That makes some sense, considering that Trump will likely not face a significant primary challenger. But Sanders (who was pegged at 14-1) also trailed a number of Democrats who are either running or considering it, including former Vice President Joe Biden (12-1), California Senator Kamala Harris (8-1) and former Texas Representative Beto O'Rourke (10-1).

As oddsmakers often do, BetOnline also had odds for a number of famous long shots, like Oprah Winfrey (50-1), Mark Cuban (100-1) and Will Smith (100-1).
