You hope he won’t make these mistakes. If you will recall, Romney was vicious to the other candidates during the primaries, then refused to go after Obama after he won the nomination. We can only hope we never see that replay again.
Yes, there were those that would not vote for him because he was a RINO and a Mormon and those folks have no right to complaiin about the mess we now find ourselves, but Romney was Romney’s own worst enemy.
fwiw, the way Trump has already gone after hillary and Sanders should give us confidence. Trump doesn’t have it in his DNA to do anything but strive for a winning strategy.
