From CNN.com:
...Trump made it clear he wanted to fill the empty [Supreme Court] seat before Election Day, presumably because he expects his nominee to side with him if the election ends up being decided by the court. If that was not enough to place [Amy Coney] Barrett in an awkward position from the start, the [confirmation] ceremony [at the White House] on Monday night went a long way toward politicizing the one institution that is meant to remain above politics.
The Supreme Court derives much of its power from the perception that it is largely independent of politics. The over-the-top event had the look of a Trumpian campaign stunt more than a Supreme Court swearing in. Barrett, Trump and their spouses waved from the balcony, evoking the image of Trump's dramatic face mask removal on a White House balcony upon returning from the hospital.
That resonance to Trump's campaign grandiosity, the partisanship that marked Barrett's appointment and Trump's own statements about the role of the court in the upcoming election, are evidence of the blatant politicization of the Barrett nomination, undercutting the court's credibility. America stands on a knife's edge; the President is sharpening that knife.
