Former Hillary Clinton spokesman Brian Fallon, a Chuck Schumer alum who is leading outside efforts to block Kavanaugh’s confirmation, is adopting tactics normally associated with the party’s far-left activists. On Monday, he roasted Virginia senator (and Hillary Clinton’s running mate) Tim Kaine for merely expressing questions about the judge’s philosophy. “We already know the answers to these questions, Tim Kaine. Stop playing political games and help us #StopKavanaugh,” Fallon tweeted.

Even more alarmingly, Fallon called for any law professor or lawyer who dares praise Kavanaugh should effectively be banned from ever serving in a future Democratic White House. This hollow threat came after several of Kavanaugh’s liberal friends at Yale Law School wrote laudatory pieces about his character in national newspapers. “Progressives should keep a list of names of the sellouts at Yale and elsewhere who are right now trying to smooth a path for the overturning of Roe and the gutting of the New Deal. They should be unwelcome in future Democratic administrations,” Fallon wrote Thursday.

These are the type of tactics that suggest the rise of a more illiberal Left, unwilling to tolerate dissent or free thought—even if it’s in the Democratic Party’s best interest not to look like mindless obstructionists.
