If the bookies are doing their jobs right, they'll make money either way. They set up the market, and the people who think Trump's odds are better than 20 percent will pay 20c for the shot at winning a bit less than a dollar, the bookie shouldn't let them buy it unless there's also someone who thinks $0.80 to win a bit less than a dollar sounds good. The bookie then holds onto the full dollar they get, and then pay out (say) 97 cents on {inauguration, electoral college vote, whatever}.

Only a moron would believe such odds, especially after happened to Brexit (odds were the same on the night before the result).

Up until a few hours before trump took Florida, the traditional news sites were discussing how big a sweep for Clinton and if Republic would loose the house.

I won £20 with a £5 stake at my local bookies. Wouldn't really count that as 'making money' though.

I must be a moron then as I won £200+ Man, that stupid is really feeling bad right now.

Sarcasm is the mark of an immature child.

Improve yourself.

I think sarcasm is a pretty appropriate response to being called a moron.

If there was a 1% chance of outcome x, and I offered you 1000 to 1 odds, would you be a moron to take the bet, just because there is only 1% chance of winning it? Please call me.

This moron put in EUR 100 yesterday at 4:1.

Bets for a Trump win were reasonable as a hedge.
