Fox News' own right-wing nutbag Sean Hannity said the following last night:
If you're going to be a family-values candidate and a family-values politician, and you don't live up to that, I think you should resign.
Of course, Hannity said this in response to Nevada's Republican Senator John Ensign cheating on his wife with a staffer's wife, not David Vitter cheating on his wife, kids, and constituents with prostitutes, but the message is quite clear. Even conservatives (heck, especially conservatives) should be put off by one of their own not living up to their own standards. Conservatives should not stand with Sinning Senators, as much (if not moreso) for the hypocrisy as the sin itself. We'll have to wait and see how principled "family values" conservatives are on this issue when it comes to David Vitter.
