Nobody should be surprised that the election and Presidency of a black person led to a resurgence in racism and white nationalism. But each dying gasp is weaker than the last. If Trump follows through on his campaign promises, I think he will unite Americans like never before against his tyranny.
Obama was elected BECAUSE of white voters not despite them. Your logic is flawed
And Hillary won the popular vote because of white voters too.
But Trump didn't win the GOP primary because of his economic prowess, or his political skills, or his knowledge of foreign policy, etc. Cruz, Rubio and others had him beat on all that. He won it because he openly berated the darkies and made people believe that he would punish people of different faiths, cultures, beliefs, and political ideology.
The last gasp of white nationalism, and the best champion they could find is a reality TV buffoon. Weaker and weaker...
