Well, I guess that too has its caveats. Hilary Clinton and Barack Obama were both vocally against same-sex marriage during run up to the 2008 election, I believe roughly the same time that the Prop 8 fight was happening. They didn't switch sides until public opinion started swaying in favor of it and I've never seen anyone hold their feet to the fire or call them "absolute scumbags" over it. Well, no one that wasn't already calling them that at least.
