I think this meme is even more dead-on now that South Carolina and 'Super Thursday' have passed.
Mayor Pete, Amy K, and now mini Mike have all dropped out and are supporting Biden. And mysteriously, Pocahontas hangs in there (as of the time this is being written) which is the same as denying Bernie support from those who will eventually become her former voters.
Coincidence??? Nope. Nobody in the DNC hierarchy can say with a straight face that this is due to anything other than them putting in the fix for quid pro Joe, just like they did in 2016 for HRC over Bernie.
The Bernie Bros, who are the same people that want to put Republicans in re-education camps, have threatened to destroy Milwaukee if Bernie doesn't get the nomination. They will have no desire to unite behind Biden if he is the nominee, because they are not Democrats and will feel no need to unite a party to which they do not belong. So, they'll use a scorched earth policy (Berning down the house, the Democrat house, so to speak) against Biden from this point forward.
Eventually they'll need to realize that their revolution cannot take place within the constructs of the Democrat party. They need to form their own party... especially if they want to run AOC for president at some point.
