Which southern states are the most libertarian?

[rebeltarian]

Looking at voting patterns in the south, for many years Republicans could occasionally pick off border states like KY and TN (Ike, Nixon in '60).  Then Democrats lost the deep south and now they can only hope to pick off the border states.  The upper south is more white and more poor, but what causes these voting patterns?  Are some regions of appalachia very libertarian/republican?  What states would a more fiscally conservative, classical libertarian Republican Party be the most competitive in?

Well forgive me if I sound ignorant, but I am a long ways from the south.  I do know that the upper south seems to vote more for economic reasons (poor whites, coal miner unions, etc) and the deep south for cultural reasons (whites pited against blacks).  Most of the south is pretty rural, so I'm guessing there's a lot of people, regardless of color, who'd like to just be left alone.  Are the deep southern states more authoritarian?
