Even if some do, they'll quickly assume that if Holder finds something "not good" on himself, he'll say, "Ooopsie, my bad! Sorry! Won't happen again.", and everything will be fine in their low-info world (except they just won't understand why the Repubs keep hounding that poor man, "He said he was sorry!!").
The low info voters don’t even know who the hell Holder is or that he’s head of the DOJ.
