AOC is too much of a culture warrior to win back the old rurals that Bernie won in '16 and lost this year. Harris corners the black vote, and like EVERY DEMOCRATIC PRIMARY, their choice is the winner.
Not, "EVERY DEMOCRATIC PRIMARY". By that logic we would have had John Edwards and Jesse Jackson.
SC notwithstanding (where Edwards only won it over Kerry by 3 points, 37%-34%), John Kerry was the primary candidate who won black voters in 2004, having won 56% of the total African-American vote in the primaries.
