Why do people have such heartburn when people change their mind? So what if he voted for clinton, so what Hillary voted for the war, so what Romney used to be pro choice. I used to drink Bud Light, now it is only Budweiser, who cares?

Your greater point is valid though and if you were referring to anyone other than Mr. Hate I would agree with you completely.
