Also, I would not be at all surprised for things to progress such that Senate Republicans will simply refuse to hold hearings on any Supreme Court nominee by any Democratic president so long as they control the Senate. After all, the American people obviously elected them to block any so-called liberal justices.
This current situation could be a foreshadowing of a future in which the Supreme Court is unable to muster a quorum (which is six justices), and just like that, we’ve lost the highest court in the land, with its attendant checks on the other two branches of government.
