I wouldn’t read too much into that (from a partisan POV). AIUI, all of the serious mayoral candidates are also Democrats. And it is a non-partisan office.
I thought you were asking the question as a joke until I read the opinion.
It’s possible that Supreme Court suspected corruption and couldn’t come out and say that was the case, but instead decided to embarrass the Judges responsible.
Yes. It’s usually the appellate courts that get to have all the fun, smacking down wacky trial court judges. Intermediary review courts rarely go off the deep end.
I don’t think the legal analysis in this case was as bad as the Supreme Court made it sound - and two judges seem to agree. But they felt they had to be really emphatic.
