Sure, Bernie has a chance.
It is not a 50/50 chance... but even 1/1024 is a chance.
I think the point is to not underestimate the possibility. Bernie has a following and could conceivably be a surprise.
Beta O’Rourke is toast, Kirsten JellyBrain is toast, The Injun is toast, The Concubine is toast.
Right now it looks like Bernie/ButtSlammer 2020 for the Dems unless Bernie gets hammered on a gaff.
Or strokes out on the podium (could happen afterwards if he is nominated too).
