I don’t believe he could have won.
He has to much of a pro-homosexual, pro-abortion, anti gun, pro obama care history.
Add to that he never articulated that invaders should be sent back to their homelands and the US southern border should be secured. Then being a hedge fund manager?...they did some nasty economic stuff to US workers. These are all the reasons those conservative white and hispanic (yeah, conservative hispanic) voters stayed home. They didn't quite trust him.
During the campaign he would not renounce his 20 year effort to homosexualize the military and the Boy Scout leadership, he gave us Romney/Obama care and he ran as pro-choice, even running pro-choice ads in some states, like Ohio.
He was a nut case loser who was a disastrous one term governor who left office with 34% approval.
