Yes yes, you can play with numbers all you want but the only two States that had NO counties go Democrat in recent elections are Utah and Nebraska.
Actually, in the 2008 election, Utah and Nebraska did have at least one “blue” county. Obama even won one of Nebraska’s split electoral votes. Only Oklahoma had all “red” counties.
Don't forget our neighbor, Oklahoma. They went solid red for McCain/Palin in '08.
Texas is an incredibly large and diverse state, Utah isn’t, in fact it is led by a single, let’s call it a “well controlled” religious group, the population is less than 3 million and it is only 1% black.
Nebraska has less than 2 million people and less than 5% blacks.
Texas has 23 million and is only 47% white.
Texas has a very natural culture of conservatism.
