The reasons appear quite murky and dubious, and the impact a high dollar political election campaign will have on the state's judiciary branch will likely diminish the role of our third branch of government. Slate offers a good perspective (hat tip to KnoxViews for the link):
"Three justices on the Tennessee Supreme Court are facing an election-year attack, not for any particular decision they have authored or even for any unpopular opinion they have espoused. No, in an ugly campaign in Tennessee that appears to be getting ever uglier, Senate Speaker Ron Ramsey, who is also the state’s lieutenant governor, is attempting to oust three state Supreme Court justices in their Aug. 7 retention elections, chiefly for the judicial outrage of having been appointed to the high court by a Democrat.
"When judicial races turn into spending races, what suffers most is not Democrats or Republicans, but judicial independence and integrity. As has been exhaustively chronicled by one nonpartisan study after another, judges don’t want to be dialing for dollars from the attorneys who litigate before them, and litigants don’t want to appear before judges who dial for dollars. All of the data shows that the effect is a decline in confidence in the independence of the judiciary and a spending arms race that spirals ever more out of control.
