As the OP, the logic goes like this... "I'm a racist. And I like Candidate X because I believe Candidate X is also a racist, based on the things Candidate X says".
Now, it's possible that Candidate X is not a racist. But if the racists are confused about it, maybe Candidate X needs to be more clear. Because the racists look at Candidate Y and "We hate Candidate Y, because they're opposed to our beliefs". No chance of misunderstandings there.
Now, Candidate X will certainly have other supporters saying "We don't believe Candidate X is a racist", but I look at them sidelong and say "Don't listen to me, listen to the racists".
