Suddenly everybody wants to explore term limits for Supreme Court justices. Welcome aboard. I’ve been on that train for almost a quarter of a century. The current argument is that life tenure is a leading cause of the increasing viciousness of our confirmation battles. But whether term limits would fix the process depends on whether we’re right about what’s wrong. Term limits are popular. Some 61 percent of Americans support them. Whether categorized by party, income, race, gender or religion, in no demographic group does a majority oppose them. Over the last decade or so, many legal scholars have embraced the idea of discarding life tenure in favor of either a mandatory retirement age or, more often, a specified number of years on the high bench – usually 18 or 15.
