Rough, eh?
Arkansas
North: Populist Democratic (mostly Yellow Dog) area
South: See above. Bubba's home turf. Larger Black population than North.
Delta: Populist Democratic. Mostly (though far from exclusivly) Black.
North West: Republican (big Religious Right element, btw) with the exception of Fayetteville and the small Arkansas coalfield (both of which lean Democratic).
Little Rock Metro: Little Rock is solidly Democratic, the suburbs are (for the most part) typical lily white sunbelt GOP strongholds.
Arkansas is a fundamentally Democratic state and the AR GOP only has a machine in the NW and the Little Rock 'burbs.
Then why has it gone Republican for the last 3 elections?
