Stop thinking that you vote "for" someone in a FPTP system. You don't. You vote against the guy you don't like.
It sucks, and I hate it, but don't delude yourself into thinking otherwise. We're playing a badly-designed game with a shitty controller and we're only allowed to press a button once a year at best.
Think Twitch Plays Pokemon, but with a lot more trolls and no moderation. There will be a constant stream of people voting to do something stupid and destructive, so you spend all of your time voting against them.
Oh, and their votes count for more, so they can win even if there's fewer of them. All we can ever hope to do is try to stop them and hope they don't fuck everything up and give themselves even more power before the next time we're allowed to pick a move.
Yay America. Greatest democracy in the world right there.
