Even changing the nominee is risky at this point. There’s never been a party that has won when changing the nominee at the “last minute.”
That’s what’s scary here, replacing him could even be more disastrous than standing behind him. Both are bad choices. We’ve been fucked into a bad choice by a party that doesn’t give a shit about its own voters.
If only literally anybody in the party apparatus had listened to reason in four fucking years instead of being like “We can cart his corpse out until he croaks like we did with Dianne Feinstein.”
