I was never a Reince Priebus fan, and thought he was an establishment guy. I feel Trump wanted to play nice with the Republican establishment when he picked Priebus,  but he now knows the establishment doesn't want to play nice. So now Trump is going to pick his own people. The new communication person is pro choice, pro gay marriage, the perfect liberal, and Trump isn't getting any high fives from the media or the Democrats. 
The best explanation of the reaction to Trump came on this site a few days after the election. Trump could cure Cancer and the media and the Democrats would blame him for eliminating 100's of jobs.
