I honestly don't see how you can be a Gillum/Scott voter. It defies all logic and reason.
My best guess of what one might look like.
Gillum/Scott voter: Nelson has been in office for far too long. We need new blood. I like what Scott's been doing for our state. I'll vote for Scott.
Also Gillum/Scott voter: DeSantis loves making a fool out of himself. I like Gillum. He's enthusiastic or whatever.
Yeah, remember how many Trump/Greitens/Kander there were? Swing voters don’t base their votes on actual issues, lol.
