As long as people remain in and fight from their particular area of privilege within the Dems then Trump should romp it in for 2020. If they are able to find one unifying voice they may be able to stop themselves from tearing each other apart. The trick will be to keep all of them engaged without totally crushing each of them. It is why I think Trump likes to engage AOC and others it makes them feel like somebody, gets their ego up. Keeps them interested in trying to make their way over the bodies of other Dems careers.
As Turning Points Charlie Kirk noted while speaking in England with Candace Owens, the Dems have Victim Olympics; each victim group valiantly struggling to be the Biggest Victim.
Liberals tearing down white male candidates for the sin of being white and male shows how bigoted liberals are today.
