Are you claiming that the party alignment hasn't switched over time?

I expect that everyone would agree Alabama is a very conservative state. It was voted solid Democrat until the late 80s, at which point the state went republican along with any elected politicians that stayed in office.

If I'm not mistaken, Richard Shelby was elected as a democrat in the early or mid 80s before being the last elected official to switch to the republican party. He stayed in office for decades and had state university buildings named after him.

The voting opinions largely didn't change over that time, only the party name they were voting for.
