In my view, the state constitution should be amended to provide that all judges, at every level in the state court system, be appointed by the Governor and confirmed by the Senate - similar to the federal process. Potential judges would still be rated by bar associations and other bodies before confirmation is considered. To keep some popular will involved, the appointments could be for the same 10 year term that judges get now when elected. At the end of the 10 year term, a judge would face a retention election - a yes or no vote on whether that judge should be retained for another 10 year term.
Pennsylvania currently has retention elections and they generally are non-partisan in nature. It is rare that a serious attempt is made to unseat a judge in a retention election and it should only be in unusual cases that a judge is denied retention. If the no vote prevails, then that judgeship would be vacant and a new judge would be nominated by the Governor and confirmed by the Senate.
Just my opinion.
