Texas has never been liberal. It's populist. The difference is that conservatives used to vote Democratic. They now vote Republican.
Texas is not populist (except for certain sections of east Texas and along the Southern border).
It's actually more conservative-libertarian in ideals more than anything else, though the population tends to be very religious.
That's interesting. I just assumed it was populist because the Socialists used to do so well there. I guess urbanization really changed things.
And BTW, off topic but I've been wanting to ask you- do you know what happened in Assumption Parish, Louisiana in 1936? ( See my thread in Overall Presidential Results).
