Still somewhat leery of it, in particular with double the term length of a Senator. The longer in office, the more attractive a target for graft one becomes. I think Senators may be the upper limit I would be willing to see without reaffirmation.
Then again, maybe you could make a longer term work with some sort of "anti-election" mechanism. You vote in/appoint/have judges nominated by the bar, whatever, and periodically, a dismissal election is held. If a certain threshold of votes for dismissal/no-confidence are cast, then that triggers a conventional election/run-off for that judges spot. In that sense, the judge no longer has to actively politik, though those vying for the spot are free to campaign to try to get people displeased enough to trigger an election.
It still seems like it may only work with a populace who stays on top of their judges, but I actually kind of like the idea because in theory, good judges would never really be upset from business as usual, bad ones would very quickly become apparent in theory, since the number of corrupt supporters would be very unlikely to dwarf the number of "victims" of the judges corrupt acts, and you get away from some of the politicization of the position except when the public clearly has a change in the winds of policy in mind, in which case the election may put the judge back in office, but with renewed attention to the change in civil sentiment.
I don't know, it just feels better to me that way. I mean I do kinda get where Go's coming from, and I semi-dig it. I just don't think judges should ever be more than arms length away from the people whose lives they impact most.
