Trump doubters, What if? See details...

By now it is well known that I am a Trump supporter.
I am neither Democrat or Republican.
I voted for Obama, and I feel he has done what he can, and was right at the time he served I believe new blood is now needed to cover where he failed, and/or overlooked. I think Trump is right for what we need now.
Clearly, most of Fluther disagrees with that.
Many have spouted their thoughts about how Obama was not given deserved credit for his accomplishments by Republicans.
So if Trump wins, and actually turns out to be an exceptionally good choice, serving the country well, would those who now doubt, ever support him, and admit he did well, or would you always carry a grudge that he won?
