In almost every majority Hispanic county and electoral district, president Donald Trump gained against his 2016 presidential performance, though he lost almost all of these areas again, most by wide margins. We also saw these shifts in polling data before and after the election where higher shares of Latino voters polled supported Trump than 2016 which proved accurate.
For example, in Miami-Dade county, the county swung 20 points away from Biden, with Trump receiving roughly 200,000 more votes than in 2016 countywide. The biggest swings towards either candidate were towards Trump in rural Hispanic counties in the southern part of Texas, a state that is currently semi-contested on the federal level on the about same level as Ohio Minnesota or New Hampshire or perhaps even Virginia.
Even in areas in states that aren't realistically contested in terms of their partisanship, this shift was still shown in places like Bronx County in New York State , California, and pockets elsewhere like Lawrence Massachusetts.
What explains these gains, especially since they were from a president that said things that could be seen as targeted against that community starting in 2016?
Note: data from elections after 2020 show these gains might not be permanent. For example the New Jersey governor election showed the incumbent outperforming Biden's showing in heavily Hispanic areas of the state at the municipality level like Union City despite doing a lot worse statewide.
