Warren has no incentive to drop out after Super Tuesday because 1) She has no love lost with Sanders and it'd be handing him votes, and 2) she has a strong case to make at a brokered convention.
Thankfully there are also a bunch that just outright didn't vote that we can try to reach out to. You're right, though... the election basically came down to lower black turnout in Milwaukee, Detroit, and Philadelphia. This is probably the biggest reason I don't mind Biden as the nominee. He's by far the most likely to get these people out.I think while the man himself is vile and stupid, his campaign team knows exactly where to target voters. They only won by 150,000 votes in 2016.
shit if they convincejust 1-2 percent of voting Black people, that's another 150,000votes
