Republican voters raised holy hell about Bill Clinton's extramarital affairs in the late 90s but when it comes to their own politicians they seem to be a little more forgiving:
-John Ensign's approval rating with Nevada Republicans is a 68/19 spread and he gets 77-82% of the vote from his party when tested against potential Democratic opponents.
-When we polled David Vitter last summer his approval with GOP voters in Louisiana was 62/19. You could make an argument that his constituents were separating his actions in office from his personal life- except that his favorability was even better at 64/20! And he pulled 74% of his party vote against Charlie Melancon.
-Republican voters in South Carolina are less forgiving of Mark Sanford, but our poll there last month still found him in positive territory at a 50/34 approval. And beyond that 58% of GOP identifiers said Sanford shouldn't resign with 75% opposed to his impeachment.
Cheating on your wife is a deal breaker for Republican voters- but only if you're a Democrat.
