McCaskill to vote "no" on Gorsuch, sealing filibuster

Trump's Supreme Court nominee, Neil Gorsuch, just got the last "no" it needed so the Democrats can meet the vote threshold to filibuster his nomination. Claire McCaskill (D-MO) wrote a Medium post about her decision today:

I remain very worried about our polarized politics and what the future will bring, since I'm certain we will have a Senate rule change that will usher in more extreme judges in the future.

Why it matters: Republicans will now have to get rid of the 60-vote filibuster threshold for judges, or allow Gorsuch's nomination to fail.
