An ass on Twitter told me last week that the collusion case against President Trump was “irrefutable,” even though special counsel Robert Mueller had just comprehensively refuted it. There are people of the Left — California Reps. Adam Schiff and Eric Swalwell spring to mind — so hooked on the falsified collusion narrative that they can’t give it up.

But most of Trump’s tormentors are more fickle, or tactical, in their affections and have ended their two-year devotion to the bogus conspiracy theory with alacrity. They’re like jilted lovers who pretend they never cared for the object of their mooncalf obsession. They’ve moved blithely on, as Mueller himself did more than a year ago, to obstruction of justice and, in particular, to the president’s repeated lies and his orders to his subordinates, such as former White House counsel Don McGahn, to lie to investigators.
