It makes me think there are a lot of closet racists and bigots hidden away among grassroots Republicans. Who else would support such a person? He has no political acumen, he has no diplomacy, he has little if any humanity. Surely some of the other candidates were more acceptable.
One of my Republican friends (in Minnesota) said she would be embarrassed to be represented by such a man. She's a genuinely nice person. She likes people. She said that Trump does NOT speak for her.
The success of his campaign may have revealed a very unpleasant side of American politics and society.
