Ppl voted for his policies, not his personality. They voted for tax cuts, jobs, border security, smaller government, Obamacare repeal.
Also, they aren't impressed by the Anti-Trump (and Anti-Bernie) propaganda NYT et al suddenly started to spout. Voters watched rallies online and then noticed the media reports weren't honest. They watched Clinton-fangirl Rachel Maddow spouting off about chair-throwing Berners - after they saw the video of the event, which clearly showed the guy grabbing a chair, but then NOT throwing it.
IOW - Trump voters paid close attention to what was really said and how and in what context. They also read leaked emails. They knew the Clinton campaign playbook:" Trump's a racist, a nazi, a womanizer, his campaign is chaos, he has no clue". Rinse, repeat. It's all theater, it's still getting repeated over and over.
I wonder what Trump has done that makes you think he's horrible. I totally disagree with that statement, and I've paid very close attention from the primaries till now.
