There’s also the fact that cartels run a lot of border towns. It’s not that border area Latinos are mad at illegal migration so much as they don’t want South Texas to be like Northern Mexico.
Also, it’s a little silly to treat Latinos as a single group. South Florida Cubans are different from everyone, basically. Recent immigrants are different from 2nd or 3rd generation ones. Ted Cruz’s full name is Rafael Edward Cruz and he’s different from people who aren’t bozos.
