So, having actually watched the interviews with these people, I’m pretty comfortable saying the younger woman is not a Trump supporter. She seemed to maybe not be the most intelligent person, but that’s not a super fair assessment from a few brief Q&As. She was becoming visibly upset by some of his rhetoric, abortion related in particular.
I also wouldn’t be surprised if they were led to an answer of “we’re still undecided” by the interviewers in conclusion to broadcast a non-partisan appearance.
In less than 24 hours nearly 400k Americans registered to vote using the specific link that she provided. That’s the number that matters. If they actually go vote that is enormous.
