The Harris bump will continue until after the convention.
I think Trump's moronic comments at the NABJ hurt him. He made some very dumb comments. He went into the lion's den, and he was offended when they treated him rudely. His comment, regarding Harris, 'she was an Indian, and now she is calling herself black'. Why? Why? Why? To use the infamous words of Hillary, WHAT DIFFERENCE DOES IT MAKE? None. He should not discuss race at all.
All he should say is I WELCOME THE OPPORTUNITY TO COMPETE AGAINST HARRIS, AND RACE IN MY MIND IS NOT A CONSIDERATION. Better he say that to blacks, who overwhelmingly are about race in their vote. Harris I expect will get 88% of the black vote voting for her only because she is black, with no thought given to her competence. None!!!
