You'd be more likely to find a Trump supporter in voice acting than you would in Hollywood proper.

I can name a few off the top of my head: Vic Mignogna, Chuck Huber, Caitlin Glass, Karen Strassman, Wally Wingert...I've heard rumors that the legendary Jim Cummings does as well, but he keeps this to himself for understandable reasons.

Granted, the sample size is much smaller, to put it mildly.
