I don’t think the day before Super Tuesday is appropriate, it should be months earlier but a week later (or earlier) would be more appropriate than March 4th.
I just don’t love the disruption to the political calendar being so direct. It’s not like we’re getting a guilty verdict the first day so it’s just ginning up the news cycle away from whatever might be topical and relevant and back to Trump and his legal woes.
We don’t know for sure what March will be like. Maybe some folks drop out and Trump isn’t leading by as much by then, and the challenger has a positive news cycle only to be drowned out by this court case again. It’s not inconceivable that this helps or hurts Trump on Super Tuesday, and I’d rather just avoid either if given the option. Let it be a court case.
