Trump's in it for his ego. He wouldn't know what to do with the Presidency if it dropped into his lap. These two reasons explain why he says something offensive and/or appallingly ignorant every twenty-four hours without fail: it simultaneously keeps him in the spotlight while ensuring he will never, ever gain the GOP nomination. (He won't run as a third-party candidate, either.)
A few earnest pundits insist that Trump's consistent strength in the polls means he represents a lot of people out there. We can't ignore those people, these pundits insist.
Come on. Indulging those people would be like indulging a four-year-old's demand for matches. We don't do that. We aren't going to let Trump's fans have their way, either.
It's summer. Enjoy the sun. Have a cold drink. And don't feed trolls.
