I think another judge did. Nelson was picked to be the trial judge.
I used to live in Seminole County, and I did jury duty once and Judge Nelson was over that case. Granted, it was a simple and apolitical case of robbery - but I thought she was balanced and reasonable back then.
All the jurors even met her after the trial was over, and toured her office. The only thing I really remember is that she had elephants everywhere decorating her office - indicating she was a Republican. (I know that doesn’t mean anything - just an interesting memory).
