"Especially after Justice Ruth Ginsburg lost her bet on her own longevity, with the rest of us forced to pay, it's astonishing that Justice Stephen Breyer would court the same risk," Samuel Moyn, a Yale Law School professor who signed a letter with several other academics calling on Breyer to retire, said by email. Another signatory of that letter, University of Houston Law Associate Professor Daniel Morales, told CNN by email that Breyer was "playing Russian roulette."... Miranda Yaver, an Oberlin College political science assistant professor who signed the academics' letter, expressed frustration about Breyer calling his health the main determinant of his retirement timeline. "We've seen egregious consequences of a Supreme Court justice who was gambling on her own health and misjudged the extent to which she would be able to serve on the Supreme Court," she said. "He's also gambling on the health of the 50 senators who would be able to confirm his replacement."
