This, from a party that has decided to gang up on one of its more successful candidates and shut him down. What they are doing to Bernie Sanders, while hilarious to watch on its own, is actually scarier from a standpoint of what happens if the Democrats EVER win the presidency and control both chambers of Congress. Keep in mind they are now talking about shutting down the rest of the primaries, and certainly the primary debates, to prevent the most gaffe-prone frontrunner in the history of the United States to add to the meme-industrial complex. (In fact, they are even talking about Biden not even debating against Trump, but for now it's just chatter.)
In short, Biden is the most manipulated Manchurian candidate in the history of the country. Pure and simple.
