The odds suggest a repeat of the 2016 Election, but just slightly.
President Trump won the Electoral College vote but not the National Popular vote that year, and the odds imply there is a 61.5% chance the same outcome will occur in 2020, according to numbers from BetOnline.ag.
Of course, the oddsmakers were grossly wrong in that 2016 Election as they heavily favored Hillary Clinton so you never know what will happen, but Vegas is right more often than not.
The online bookmaker has head-to-head odds for individual matchups against Trump for the electoral vote, and Michael Bloomberg is the only candidate favored over the current POTUS.
For the popular vote, the "field" is a favorite against Trump.
There is even a political double result prop bet that gives odds for the four electoral/popular vote scenarios.
