I'll tell you one thing that will happen: I'll win $2 from my employee.
"OMG, you bet to support Trump?" My wife asked. No, of course I do not support Trump. But for 2 years I'd had to hear guy talk about how it's mathematically impossible for Trump to win because there are too many women and PoC voters. So, during the Summer I asked him if he wanted to wager on it. I think guy is ignoring the crazy electoral vote system and underestimating 30 years of hatred toward Hillary Clinton. The fact H isn't overwhelmingly in the lead is a bad sign. He thinks I give too much credence to polls, which ultimately serve to keep people interested in polls until the election.
And that's $2 if he gets elected. Trump wouldn't have to get sworn in.
In any case, my guy has been annoyingly cocksure and it's worth risking $2 to be able to hold over him, at least until the bombs start dropping.
