Any expansion of the court needs to include term limits. I like the method that basically replaced a judge every 2 years. That way each President gets two court appointments. Also, build language in there so it is impossible to filibuster a court appointed. Like, you can't filibuster and it only takes 1 person to bring a nomination to a vote.I’d be fine with each side gets 2 and all 4 are approved by the Senate as a group. Keeps the current balance.
