You can’t assume that just because he’s in a union that tells him to vote for Democrats that he does. I’m a teacher so I have no choice but to be in a union and I’ve never voted for a Democrat. Not once in the 20 years I’ve been voting. I’m not the only conservative either. In my grade level there are six teachers and three of us are conservatives - we’re just not vocal about it. (I’m a libertarian but I generally vote R.)
