What did Donald Trump do today?

He tweeted.

At 8:37 A.M. this morning, Trump tweeted out what for him is a fairly typical campaign message:

Trump's opinion about his rival's intelligence within moments of his retweeting a video of one of his own supporters screaming "White power!" at counterprotestors in Florida.

The tweet was deleted by his staff a few hours later, while Trump was on the golf course. A spokesperson later said Trump did it accidentally, not knowing what was in the video.

So what?

• White supremacists don't support politicians they don't think have their interests at heart.

• This is not what a high-IQ person would do in this situation.
