Simple answer: Because he isn’t as bad as the current ass-clown.
If Obama is elected, then it’s game over. The next President will likely appoint two Supreme Court justices. If Obama gets to make the nominations, we’ll get Bill Ayers and Al Sharpton (or the stealth equivalent). Obama MUST be voted out. I don’t know who Romney would nominate, but I doubt his nominees would be Alinskyites.
IMHO it's game over already and we just don't know it yet. Economically we have past the point of no return. We can't recover from 16 Trillion in debt and 100 Trillion in unfunded mandates. It's just mathematically impossible. Socially we have past the tipping point where over half of the people rely on the other have to produce. The Rats are taking us over the cliff at 100 mph (in a Volt), the GOP is taking us over the cliff at 80 mph. the end result is the same.
Romney as Governor appointed leftists to the bench. Yes, LEFTISTS.
He has a record on the issue. Stop ignoring it.
