Some people think hypocrisy is not a sin in politics. Indeed, some people think one is so integral to the other that they can't imagine what would be left if you took the hypocrisy out of politics.
I'm not one of them. In fact, I'd have to say that I think hypocrisy is one of the greater political crimes. Not because I particularly think that politicians are more upstanding than the rest of the public, though I wish they were.
