I would have to go with Romney. His habitual lying is frightening similar to Clinton as are his denials when he gets caught.
Romney has some truths behind what he is says. Clinton had no truths whatsoever behind his statements. I disagree with your opinion.
I realize you are on a crusade to tear down the Republican candidate of the day who best threatens your candidate. So if your man does not get the nod what are you going to do?
