Any black American who has the gall to call themselves a Republican is attacked with a viciousness that is stunning. So a Michael Steele (who has now bent over to them to try and deflect some of the viciousness) or a Lynn Swann will get both barrels.
Other than that, there is no one the left hates more than Rush Limbaugh. Sarah is a close second. The reaction of the Left to either of them is like throwing water on the Wicked Witch.
