Nobody LIKES pompous arrogant assholes, but when you need something done, sometimes it takes one.
If I'm facing a life sentence, I want the pompous arrogant asshole attorney
If I'm facing open heart surgery, I want the hotshot surgeon with a God complex etc.
Trump comes off as more of a pompous arrogant asshole than the politicians he has to deal with, because he isn't one of them. He didn't spend decades honing his fake persona, and manicuring his financials etc. But make no mistake, those politicians are even more insidious than him.
It's just that Americans are, by and large, ignorant and yes, in a lot of cases, willfully so. They vote based on feelings. Adults don't vote on 'feelings', they vote on issues.
