Is Texas "Southern" or "Southwestern" or both/niether?

[Lunar]

It really marks the distinct point where the South hits the Southwest.  Regional classification terms probably have more blurred lines than most classifiers due to the arbitrary nature of drawing fake political lines over geographic territories (people fight and die for these lines though, so whatever).

I say, come up with a key list of standards for the idea of the defining state.  If a state meets some of the classifiers it could still be considered Southern (just like a sex change person could be considered a woman or a non-knobby door handlething could be called a doorknob), just possibly less so.

For Southern we have things like:
*Population speaks with a Southern accent
*Fought for the Confederacy
*Considers themselves Southern, ex-Cotton economies
 *Geographically in that area
*Cultural ideas that come with being "Southern" - actually liking breakfast and suggesting to your friends that you get breakfast with them, eating biscuits & gravy, enjoying NASCAR etc.

For the Southwest we have things like:
*High Hispanic population
*Arid climate
*Geographically in the Southwest, territory acquired during the Mexican-American war especially
*Etc?  The Southwest is a surprisingly diverse place filled with a diverse group of potential ciites like LA and Las Vegas and Salt Lake City.

Anyway, I think it's pretty clear that Texas is roughly a 85-100% fit for both of these categories.
