The Washington Post’s creepy exit poll bar chart:
It’s possible that the Hispanic plurality for Bernie is largely a function of Latino voters being younger, because the generation gap among Democrats is huge:
Clearly, blacks are voting in a racially distinctive manner, but it could be that Hispanics are mostly voting like young non-college Democrats.
Biden’s coalition of blacks and older centrist whites is unusual. One predecessor might be the 2001 mayoral election in Los Angeles when Westside white liberals decided it was time for a Latino mayor, Antonio Villaraigosa. Blacks and the more moderate/conservative whites in the San Fernando Valley didn’t like the sound of what the Westside had cooking, so they united behind a white liberal, Jim Hahn, whose father Kenneth Hahn had been very popular among South-Central blacks.
This white-black coalition worked, electing Hahn. But it soon came apart over whether to give the black LAPD police chief another term. Mayor Hahn decided to let him go and instead hire Giuliani’s old brilliant top cop Bill Bratton, which did a lot of good for the crime rate in L.A. But Hahn’s courageous decision smashed up the short-lived white-black coalition, with the blacks deserting for Villaraigosa in the rematch in 2005.
So Biden’s current coalition isn’t unprecedented, but it also has natural fault lines.
We’re seeing something similar in the LA District Attorney election, where the anti-crime black lady incumbent Jackie Lacey is trying to get 50%+1 in the 3 person primary to avoid a runoff, probably with the Soros backed George Gascon. She’s currently at 51.7% but final vote counts in California take weeks.
