Why did Trump claim at NABJ that Kamala Harris is not black, and then double down on that claim last night? Bill Kristol thinks he did so for this reason:
"Trump may well have decided that to win, he has to increase the salience of race in this campaign. Sadly, this is not a new gambit in American politics. And sadly, it sometimes works."
And:
"Harris shouldn’t be left alone to defend herself."
