Does this impact Governor Palin's advice that South Carolinians cast a vote for Gingrich (rather than, say, Santorum)?
I'm not a Gingrich fan, as regular readers know. If I were, I would wonder whether, in the unlikely event Gingrich won the nomination or the presidential election, his victory would effectively require Republicans to become enablers for (or justifiers of) objectively bad personal behavior. The process of continually justifying or minimizing Bill Clinton's behavior meant that many Democrats ended up having to defend or minimize behavior that actually appalled them personally.
Once standards for proper (right) personal behavior erode, it's awfully hard to get them back. Republicans had better be pretty darn certain Gingrich is worth reducing or eliminating their standards for a president's personal character and behavior -- and pretty darn certain that he truly IS the changed man he claims to be.
