Always impressed to see a place like Elliott County stick with Democrats, even when other places like it abandoned the party years ago. More than anything I guess it intrigues me. What convinces people there to keep voting Dem, even as Democrats sometimes seem to go against their cultural sensibilities?
Poverty+labor (a factor in Obama's drop in WV/KY may have been that the UMW declined to endorse anyone this year).
The other county which has never voted Republican (Brooks, Texas) is also very poor, though it's Latino, not Scots-Irish.
