Latinos on our borders suffered the most when they were open, which is why Trump did well there.
Now that the borders are closed the far bigger issue in these communities (as throughout the country) is the economy. This is currently stressed due to inflation and Trump was in charge. Anyone in charge when this happens will be punished at the polls. It will be interesting to see how the Dems will address the inflation issue and how this will work out. They don't have a great record handling this issue because it requires fiscal restraint.
