If Trump is the nominee, republicans will vote for him. He will be supported by Christians for the Supreme Court, the billionaire class and their minions for taxes, and racists for his anti-immigrant policies. He will generate no democratic support and his appeal to independents is not strong. I would love to see a bruising battle for the nomination, if he hasn't died, resigned, or been impeached by then.
Only the stupid ones. Unfortunately there seems to be a lot of stupid around.......
