The red states need to pass laws prohibiting the scum that flee the blue socialist states they’ve destroyed from voting in statewide elections for a period of ten years, allowing amnesty (and the ability to vote) only to those who can prove they have been registered Republicans for at least the past two elections.
This kind of legislation might at least slow the Democrat scum who migrate like locusts and destroy one state after another.
I don't know if you're joking, but that would be blatantly unconstitutional. As the Supreme Court has ruled, under the 14th Amendment, "citizens can pick their states, but states cannot pick their citizens."
