Also, I wanted to say that the more open Trump is about racism, the more he will turn people off. There are a lot of people who are pretty much racists, but they would never admit it, even to themselves. These are people who cross the street when they see a black man coming toward them, but would never dream of saying the N-word and think Martin Luther King had a dream about something involving ending racism and that was good.
Those people will not want to be associated with Trump and Vance the more overt they get.
