This afternoon, President-Elect Biden introduced his first Cabinet picks, all of whom are highly qualified and experienced. None is remotely controversial.

Senator Marco Rubio tweeted that he would oppose them all.

One reason he gave was that they had Ivy League educations. On Twitter, one of the many responses was a list of Trump Cabinet members who had gone to Harvard, Yale, and other Ivies. Trump went to UPenn, an Ivy, and Jared Kushner’s dad gave Harvard $2.5 million to grease his entry to Harvard.

Will the race to grab the Trump know-nothing base, e.g., the race to the bottom, encourage Senate Republicans to block any appointments Biden makes? That would create a constitutional crisis and destroy Biden’s Presidency before it begins.
