New Jersey’s senior Senator, Cory Booker, seized the floor of the upper chamber for an epic anti-Trump rant that, at this writing, has stretched past 21 hours.

We bow to no one in our admiration for the 40th president, but the idea that Mr. Booker has anything to do with Reaganism is the biggest corker of his career.
