You really did not say anything, so I was left in a position to guess.

Saying that a Mexican cannot be biased as a judge is itself a racist comment.

So it’s reasonable for Trump to be leery of a Mexican American judge.

Any analysis on whether the disparity is the same, greater, or less between elected and appointed judges?

You better not be upset when Trump says that Mexican judges can’t be fair to him if you are going to turn around and say that white males cannot be fair to people of color and women in their trials.
