do I know how well Bernie would do with African-American women or suburban white women, in a general? no.
actually, yes we do. look at South Carolina, where Biden beat sanders in the African amareican vote by over 50%. or super Tuesday, where he consistently beat sanders in that demo and carried white suburbs. Virginia, where Biden spent literally nothing.
also, Bernie's numbers among African Americans have not improved since the 2016 primary. he's essentially been running for president for the past five years and nothing's changed, what leads you to believe it's going to happen in the next few months, particularly against an opponent who is generally liked by that voter segment?
you know one thing I do know?
well, here's another one: the blue wave that allowed the dems to win the house in 2018 consisted of literally all moderates. that's not bullshit polling with margins of error, that's actual votes cast by people motivated to get off their ass, one of the biggest mid-term voter turnouts ever. to support moderate candidates. AOC campaigned in Texas for a house progressive who ended up getting crushed by a moderate dem. Bernie's brand of progressive populism is great but just doesn't play outside liberal districts. it's not a national feeling. the fact that he hasn't expanded his base in five years proves it. you want data? that's some data, right?
