It is all political posturing, she just got confirmed for the DC Circuit last year 53-47. Be honest, you guys would be against any S Ct nominee Biden puts up, the reasons may differ from one candidate to the other, but you still would be against the choice, as would Cruz, McConnell, Hawley, et al. Anyone could see from 100 miles away that the vote is going to end up 51-50, or maybe 51-49 if a Republican breaks ranks, but Jackson is going to get confirmed.
As for me, I preferred Childs from South Carolina, a state court judge who went to public universities, breaking up the Harvard-Yale-Columbia Ivy League cartel.
