Funny that you point that out and you ignore something bigger.
Bernie has huge support with Hispanic supporters.
Biden's entire campaign is run on his "electibility" but that whole thing is based on what, the fact that he was a long term Senator in Delaware? That he got his ass drummed in2008 with his electability? That he didn't even dare to enter the race against Hillary in 2016 because of his electability?
Most poeple who voted for Biden according to exit polls were Black or never Trumpers. Someone couldn't be a never Trumper and not vote for Bernie so that segment of the base is gone.
I'd like to see your numbers on Bernie being strong with "less well educated" white men.
"At the same time, Sanders was formidable in his core groups. He won voters younger than 30 by a smashing 58-13% over Biden and those age 30 to 44 by 44-20%. “Very” liberal voters backed him by 47-18%, independents by 38-24%. On one of his signature issues, he won voters who support a government-run, single-payer health care system – 56% of all those who voted – by 43-22% over Biden."

Bernie wins youth, independents, people who want a single payer health care (which is polling over 50%) BIden is doing well with Republicans who don't like Trump and conservative Democrats. Which personally I'd rather them **** or get off the pot.
