Democrats have way fewer drooling brain donors than the Republicans do. I’m sure he’ll get some votes, but he’d never be able to pull the kind of crowds Trump was able to on the conservative side. Democrats are also way less likely to support a DNC candidate at any cost as they don’t see politics as a team sport where their “side” has to win at all cost (for better or worse). If the DNC truly did run a candidate as horrible as him in the general election they would 100% lose because a significant portion of liberal voters would vote 3rd party while the conservatives would fall in line like the good little serfs they are.
