Regarding the Oct. 28 editorial “Have Republicans learned nothing?”:

Sen. Ted Cruz (R-Tex.) signaled an unfolding attack on the Constitution when he said, “There is certainly long historical precedent for a Supreme Court with fewer justices.” He hinted that if Democratic presidential nominee Hillary Clinton wins, he would block any nominee to succeed the late Justice Antonin Scalia. Sen. John McCain (R-Ariz.) suggested a block of all justices she might name. GOP lawmakers are threatening to extend the scorched-earth campaign tactics of 2016 after Inauguration Day.

Tellingly, their remarks expose the lie behind GOP senators’ stonewalling of the nomination of Judge Merrick Garland, despite Republican leaders’ talk of filling the vacancy after the presidential election. Once the president nominates, the Senate must take seriously its constitutional obligation to give that nominee a fair hearing and a timely vote.

A cynical, post-election, partisan power grab must not be allowed to engender a further hobbled Supreme Court.
