Laura is right. But...
I live in a rust-belt state. Folks in my neck of the woods are mainly blue dog Democrats. Trump won my state because those blue dogs want to see industry come back to the US. And Trump promised that. The immigration thing is definitely secondary.
If in 2020, the factories are back, Trump will probably win my state again. But if those empty lots are still empty, my state will probably flip back to Democrat.
“The immigration thing is definitely secondary.”
You don’t seem to understand the problem. Read Ann Coulter’s ‘Adios America’.
