People voted for Oboma because he'd be the first black president. It made him a celebrity. His devastating history didn't matter.
Donald Trump had a TV reality show. He, like oboma, is running as a celebrity. His far left wing progressive history doesn't matter any more than obomas did.
People like voting for celebrities. They think maybe someday they could get a thank you card with an autograph.
Fine. I can see fame being an influence. If it were Tom Selleck, or Phil Robertson (as instances), I'd probably be endorsing them too.
It is the principles that matter. Fame means nothing without the principles we stand for, else the principles we stand for are not principles.
