Justice Ruth Bader Ginsburg was widely, and deservedly, criticized for her refusal to retire from the Supreme Court at a time when a Democratic president could have chosen her replacement.
Justice Stephen Breyer is making a similar and arguably even more egregious mistake.
The evident indifference on the part of Democrats regarding the failure of Justice Breyer, 82, to announce his retirement is apparently a product of the assumption that he will do so at some point during the current Congress and that therefore whether he does so anytime soon is not particularly important.
This is a grave mistake.
Consider that because of the extremely thin nature of their Democratic Senate control, the shift of a single seat from the Democrats to the Republicans or even one vacancy in the 50 seats now controlled by the Democratic caucus would probably result in the swift reinstallation of Mitch McConnell as the majority leader.
What are the odds that something like this — a senator's death, disabling health crisis or departure from office for other reasons — will happen sometime in this Congress's remaining 22 months?
Alarmingly for Democrats, if history is any guide, the odds are quite high. Since the end of World War II, 27 of the 38 Congresses have featured a change in the party composition of the Senate during a session.
The probability that such a shift may occur during this particular Congress may well be even higher than that. At the moment, no fewer than six Democratic senators over the age of 70 represent states where a Republican governor would be free to replace them with a Republican, should a vacancy occur.
