Oh yeah, he's doing great. He just called his sister his wife and have been describing today as Super Thursday, but he's the man!
All that's happening is that the DNC is giving the Bernie Bros the old heave ho. Then they will throw poor Biden into Trump's jaws and look forward to a more opportune time in 2024. What the current Dem leadership can't have, is Bernie, win, then purge them, and then Bernie's folks pick the 2024 nominee. It's pretty common for the US to switch parties after two terms, so the DNC establishment is pretty committed to making sure Bernie gets the Shaft.
"My reach does exceed our grasp, because there's no doubt in my mind we can grasp whatever we reach for." - Biden
Churchillian!
