Dan Pfeiffer: “There is a liberal fantasy that Emperor Trump will one day have his no-clothes moment, when the fact that he is a con man, a fraud, and a clown becomes apparent to all. This idea — that we are just one revelation away from millions of Trump supporters taking off their MAGA hats and seeing the light — is the undercurrent of so much Trump discourse on MSNBC and elsewhere.”“That moment is never coming. Polarization and partisanship are powerful drugs, and most of Trump’s base would follow him off a cliff rather than admit his critics were right. However, the coalition that put him back in office just over a year ago appears to be on the verge of collapse.”
