I'm always pretty optimistic, I read the Pat Buchanan books, they are in our library about the potential change the US could face. We have already seen not just California but to an extent, Virginia and Colorado change. It just doesn't look good for Conservatism over the long run. Even National Review seemed to be saying "legal immigration" is as much of a culprit as anything. That's why to stave this off, I've gotten behind Romney and Trump to try and stop this though Paul Ryan seems a bit of an amnesty-giver, I don't think Romney at least per official position, saw it this way.
