The way the republicans have played this game is so dirty, that you can't expect people to forgive. We can not reward such a divisive character like Donald Trump with his racism, xenophobia, mysogny, insults and bullying with a successful presidency.
Honestly I think the democrats should do the best the sabotage him and make sure everything he does fails. It should teach them a lesson that there is no reward in playing dirty and confrontational.
If we reward this behavior it will only get worse.
It is sad to say, but for the long term benefit of America it is probably better if it gets run to the ground over these four years. Then America will be spared for such leaders in the future.
