Some are absolutely exactly who you have described. Some want to pretend that it's really the Democrats that are super racist so they keep around their tokens so they can say "I have a black friend!". Others are entirely disengaged and don't give the slightest shit about it one way or another.

They're not a monolith and they have to pander to each of these groups differently. For the first they pander to literal members of organized Nazi groups and peddle shit like the great replacement theory. For the second they appoint folks like this and point out folks like Gregory Cheadle and say "That's my African American!". For the third they yell about how prices have gone up and promise they'll bring them down with voodoo economics. It doesn't matter that the economics are lies. It doesn't matter that they're using women and people of color as props. All that matters is they tell enough conflicting things that everyone gets to latch on to their own lie and say that everything else was just bluster.
