No, the judicial branch ideally should not be subjected to popular opinion. I recognize that it's not totally devoid of influence from public opinion now, but electing them would be even worse than the status quo in that regard.
Yes, but only if it's a nonpartisan election.
Elections are always partisan.
I meant that judges shouldn't run as members or nominees of political parties. A ideological divide in many of these races would be inevitable, but party politics would be very bad indeed.
What's the difference? Even if (D) or (R) aren't on the ballot, there's going to be default Republican and Democratic candidates. Hell, Supreme Court justices have default political affiliations
now, despite the fact that they're not elected.
That being said, judges should face term limits.
This would result in huge inconsistencies in constitutional law, because judges would be frequently replaced, and new judges would throw out previous rulings commonly.
