It’s already been explained to you that justices accede to their positions by wildly different means depending on the jurisdiction. In fact, I think it’s been explained several times. Did you miss it, or did you ignore it?
These blanket generaliz(s)ations don’t make you look smart — they make you look uneducated.
Obviously you’ll post whatever as is your right but it’s pretty tiresome to those of us over here who actually vote for judges and/or watch judges get appointed, deal with judges, know judges, etc.
