What should we do about the Supreme Court?

 Erwin Chemerinsky says because the Court's approval rating is so low, it's time for a change to restore legitimacy for the Court.  He says 18-year term limits are the answer:

The United States is the only democracy that gives members of its highest court life tenure. In fact, few states provide such a guarantee to their justices and judges. Life expectancy is much longer now than it was in 1787, when the Constitution was written. From 1787 through 1970, Supreme Court justices served an average of 15 years; justices appointed since 1970 have served an average of 27 years.

Clarence Thomas was 43 years old when he was confirmed, in 1991. If he remains on the court until he is 90, the age at which Justice John Paul Stevens retired, he will have been a justice for 47 years. This is too much power in one person’s hands for too long. Also, too much now depends on accidents of history, namely when court vacancies happen to occur. President Richard Nixon appointed four justices in his first two years in office; President Jimmy Carter picked no justices in his four years. President Donald Trump picked three justices in four years, while the previous three Democratic presidents served a combined 20 years in the White House but selected only four. Staggered, 18-year, non-renewable terms would mean that each president would make at least one nomination every two years. My sense is that there is bipartisan support for this reform, which would require a constitutional amendment. Rick Perry, the Republican former Texas governor, argued for it when he ran for president in 2016. Liberals support it as well. Term limits should be applied to current justices. Otherwise, they wouldn’t be implemented for decades. Amy Coney Barrett was 48 years old when she was confirmed, in 2020. If she remains on the court until she is 87, the age Ruth Bader Ginsburg was when she died, she will be a justice until 2059. The question is whether any constituency cares enough about this issue to do the hard work of getting the Constitution amended. That would mean lobbying Congress to propose the amendment and then mounting a campaign for its adoption by state legislatures.
