Given the choice between hearing a stranger talk about stuff you don't understand on TV, you'd choose the one you 'like' more. It's that simple really.

Trump is no more a leader to you or me, than Brad Pitt. It's just some person on TV you never come in contact with.

A better question is why is there voting for a president, by people who don't understand anything about what it takes to be good at that job. Absolutely nothing for the vast majority.
