Trump's support in South Carolina is built on a base of voters among whom religious and racial intolerance pervades. Among the beliefs of his supporters:
-70% think the Confederate flag should still be flying over the State Capital, to only 20% who agree with it being taken down. In fact 38% of Trump voters say they wish the South had won the Civil War to only 24% glad the North won and 38% who aren't sure. Overall just 36% of Republican primary voters in the state are glad the North emerged victorious to 30% for the South, but Trump's the only one whose supporters actually wish the South had won.
-By an 80/9 spread, Trump voters support his proposed ban on Muslims entering the United States. In fact 31% would support a ban on homosexuals entering the United States as well, something no more than 17% of anyone else's voters think is a good idea. There's also 62/23 support among Trump voters for creating a national database of Muslims and 40/36 support for shutting down all the mosques in the United States, something no one else's voters back. Only 44% of Trump voters think the practice of Islam should even be legal at all in the United States, to 33% who think it should be illegal. To put all the views toward Muslims in context though, 32% of Trump voters continue to believe the policy of Japanese internment during World War II was a good one, compared to only 33% who oppose it and 35% who have no opinion one way or another.
