But yes, the current condition of the court is shameful. Presidents appoint justices. Republicans have won the popular vote for president ONCE in the past 32 years. And yet 6 out of 9 justices have been appointed by Republican presidents.
To me, it's always been a good idea to study some ideas - (1) expanding the Court and then selecting randomly a subset to hear any given case (which is the way that the Circuit Courts usually operate) in order to cut down on the importance of any single judge or (2) having term limits so each President gets to have 1 or 2 appointments. Or something else to get out of this morass of the Court zinging one way or the other depending on how many appointments any single President has and the two parties always voting against the other parties' nominees regardless of qualifications and credentials.
I guess I was wrong.
