Not really.
When I was young, Texas was totally Democrat. Carry over from displaced persons and Reconstruction under the Radical Republicans. That lasted 150 years.
Note: I was never a Democrat. My first presidential ballot was cast for Richard Nixon.
True, but back then Texas Democrats were far more conservative than Northeastern Republicans.
I guess when I say West, I mean the West coast states and those adjacent to them, including NM.
I also realize the South largely flipped its political polarity from 1976 - 1992.
