Will President Donald Trump spend four years in the White House?

William Hill, whose name adorns the sports book at Monmouth Park, is taking bets.

The odds are 11 to 8 on Trump quitting before his term expired, a 42 percent chance.

And the odds of loyal Republicans changing their tune and impeaching the controversial president were set at 2 to 1.

There has been more betting action on impeachment than whether Trump will fulfill his campaign promise and have Mexico fund a wall along the U.S. border, William Hill spokesman Graham Sharpe said.

"Speculation about a possible Trump impeachment has now overtaken ... whether he will or will not build the wall as the most popular presidential betting proposition we currently have," Sharpe said.

Why might Trump not serve for four years? The Auditor scrolled the odds on the website of Dublin-based Paddy Power and saw odds of 3 to 1 that Trump will be officially accused of colluding with Russia.

If he lasts four years, Trump was the favorite for re-election at odds of 6 to 4, according to Paddy Power. Vice President Mike Pence was second at 7 to 1. Among Democrats, U.S. Sens. Elizabeth Warren of Massachusetts and Tim Kaine of Virginia, the party's 2016 vice-presidential nominee, led the pack with odds of 11 to 1. U.S. Sen. Cory Booker (D-N.J.) ranked seventh among Democrats with odds of 16 to 1.

And there were other bets:

Could Russian President Vladimir Putin name an airport after Trump? The odds of that happening were 12 to 1.

There also were odds of 100 to 1 on Trump selling Alaska back to the Russians.

That may sound ridiculous, but remember Trump was a 150 to 1 longshot when he began his presidential campaign.
