There's no use arguing with them. If things don't go their way, they will just disappear like several overconfident Republicans posters did after 2012. Or they will claim the Republican candidates that they praised were just crappy or not conservative enough to win.
^^^exactly. Every election we get a wave of new right-wing hack posters on this forum who think the Republicans are going to win every race, that Colorado is still a tossup swing-state, this forum is full of Democratic hacks, etc. And then the election comes, it turns out they were completely wrong, and they never post here again.
