High voter turnout

Trump

Well seeing as that Trump is the reason why, I'd say him.

Hillary equals low enthusiasm. I have a hard time believing anyone is excited to get out and vote for her. Just look at her stump crowds-- low energy doesn't create high poll turnouts

Everybody always claims high turnout will help their side, but the reality is that only one party consistently files protests and other actions complaining that polling stations are staying open too long, too many people are being allowed to vote, people's names should be stricken from the voting rolls, etc. Literally every single partisan battle on elections, voting requirements, etc. has involved the DEMS wanting more people to vote and the GOP wanting fewer people to vote. It's pretty clear which side benefits most and which side is hurt when turnout is high across the board.

I don't see how that could be anything, but good for Trump.
