Not sure exactly what the colors means, but to describe MD demographics to anyone who cares:
Western MD = Appalachia
Central MD = DC/Philly-style Mid-Atlantic upper-middle class; DC suburbs skew a bit more socially liberal than the rest of the state
Baltimore = >50% black, poor city
Eastern Shore / Southern MD = similar to rural/agricultural upper south (tobacco/corn); think NC/VA, not SC/GA.
Border counties: Western/Central = Frederick + Carroll; Central/Southern = Charles + Calvert; Central/ES = Queen Anne's, Harford.
Outliers: Prince Georges = high black demos; Montgomery = skews affluent + liberal.
Typically Democratic: Baltimore City; Prince Georges; Montgomery (urban + inner suburbs)
Swing: Baltimore County; Howard; Anne Arundel; Charles; Harford (I-95 corridor)
Typically Republican: everywhere else (west, east, south)
Projection: Obama +18 (58/40)
Very nice and I agree with the exception of Anne Arundel and Harford. D's still have a party registration advantage in both, but neither are swing counties. I'd place Hardford and Anne Arundel in the Typically Republican column.
