I believe Nevada has only two blue counties, Clark (Las Vegas) and Washoe (Reno), but they control the state’s politics.
Vegas ate Nevada long ago. I don’t think Reno is big enough to have much impact on the state’s politics but Las Vegas has just blown up in size and influence.
All it takes is one major city to completely turn a fairly rural red state blue. Seattle completely ate Washington State. Virginia has been completely swamped by D.C.
This is why small states like Idaho and South Carolina have to be very careful. It doesn’t take a huge amount of people moving into one major city to overwhelm the politics of such small states. Idaho is 2 million and South Carolina is 5 million. When liberals flood Boise and Charleston, those states are eventually going to flip.
It is terrifying how the big city liberals are flipping all of our remaining red states. We need to flood these states with conservatives. If you live in California or New York, do America a favor and move move and save these smaller states and others like them.
