It must be ’90s week in American politics. Bill Clinton was on the New Hampshire campaign trail Wednesday. On Tuesday, MoveOn.org endorsed Bernie Sanders, D-Vt., who has long led Hillary Clinton in the Granite State in his quixotic bid for the Democratic presidential nomination.

It feels like just yesterday, not the 18 years that it actually is, since MoveOn was founded for the sole purpose of shouting down and shutting up the many women who were at that time accusing Mr. Clinton of sexual improprieties including rape and sexual assault.
