Our Minnesota system isn't perfect but it is probably as good or better than any other system. Really bad judges sometimes get voted out. Decent judges are generally protected from political pressure. While I would prefer that only lawyers elect judges, the civilian community is unlikely to find that palatable. Your poll questions are too simplistic a response to the issue.
Judicial selection is too important to be removed from the electoral process.
Judges should be subject to removal by a body such as the state legislature. The appointment process is far more political than any proposed election, and should be dismantled in the best interests of the courts, the parties, and justice. The state should abandon judicial elections and follow the federal system of appointment and retention. You can remove a judge from politics but you can't remove politics from a judge. While politics can never be removed from the judiciary, the judiciary can be freed from the rigors of partisan politics and the pressures of campaigning for reelection.
