She will face the same penalty as Lois Lerner. Nothing
Laws are for conservatives, not liberal apparatchiks
Her big problem now IMHO is not the law, but the fact that Trump looks likely to be her opponent, and he is not going to succumb to media to pressure to drop the subject as any other Republican would.
So the problem becomes a political one. And if she begins to look like a loser they’ll kick her to the curb, sure as rain.
