Political Correction is going to be a major factor going forward. It's going to allow Democrats to quickly vett Republicans that decide to become spokesmen for Republican messages. After all, a message is really only as effective as its messenger.
Consider the case of Darrell Issa. Is this really someone the Republican Party wants out front, serving as its messenger for anything? It looks to me like Darrell Issa could run a seminar on how to do shady deals and get away with them.
