Latinos are going to be the “new white ethnics,” i.e. minorities that move from left to right as they become more integrated into US society, like the Germans, Irish, Italians, Poles, Czechs, etc. before them.
Krystal and Saagar discuss a number of polls including an Economist YouGov poll that breaks down the Latino vote among candidates, with Biden at 49% among Latino voters and Trump at 35%. Another poll from the UpShot shows Trump gaining ground on non-white older voters, and a Fox News poll compares the candidates in battleground states.
