South Dakota wasn't the only one...

Voting for Judicial Independence - New York Times:

Published: November 2, 2006

Nearly obscured by the struggle for control of Congress, there is another important battle in a handful of states over measures aimed at punishing judges for their official rulings and making them more captive to prevailing political winds. These measures all hide behind the superficially appealing but profoundly misleading banner of judicial accountability. And, taken together, they add up to an assault on a fair and independent judiciary.

The others include

• Colorado - put a 10 year term limit that's retroactive, kicking out a lot of qualified judges very quickly
• Oregon - a redistricting that would give a backdoor "excuse" to ousting judges from Portland
• Montana was going to have a means of "Recalling" judges, but the state court there discovered that the signature gatherees responsible for getting it on the ballet were all out-of-state and were filled with fraud

Plus, the South Dakota measure wasn't even proposed by someone from South Dakota - It was a Californian, Ronald Branson, who wrote the proposal.
