That applies across the board, and I suspect is a personality trait independent of political alignment. I've witnessed people on the right who were against handouts or abortion until they were personally impacted.

When there is a real personal cost, a good chunk of people become surprisingly flexible about their politics, or spectacularly fail to resolve the cognitive dissonance and resort to "My circumstances are different."

I have seen people on the left preach about banning guns until they got into an argument with their neighbor and ran over to my house to borrow a shotgun. I still don't know why I let them have it. I never got it back.

We all hold beliefs that were never really tested. You never know how strong your principles are until they are treated by circumstances.
