Hoe_Math, a pretty smart dude, identified a subset of the right with this tweet (archive). A quote from it below:

What the left is not aware of - and amazingly, cannot become aware of - is the "former leftists" segment. These are the people who never thought they'd be voting red, but could no longer ignore how ridiculous the left had become. They did not want to be surrounded by retarded psychopaths. These are mostly converts from the "sheltered" leftist section.

The former leftists haven't changed their beliefs, they simply don't want to be part of Team Psychopath. They're still retarded, though.

I'm sort of okay with them coming for the ride if they just vote correctly and stay out of people's way when it's time to crush communism, but more and more I think they'd be the first turncoats. Embrace new allies, sure, but be wary for throwing all your trust at them.
