Well the "good old boys" of Florida seem to be drifting pretty steady toward Republican...
Maybe in FL but not where I live.
Maryland has voted Dem for 150+ years because of the "martial law" deal with Lincoln.
Some of the ridgerunners still see Republicans as the "Federals" [revenuers, etc] and as ridiculous as that may see to us *now*, it makes perfect sense to them.
Lots of Scots/Irish here and they hold grudges forever.
FWIW, I was a Dem until the 80s myself and my kin have voted loyally Dem from Lincoln clear up to Reagan.
Western MD is not unique in this.
Southwestern PA [mountains] and the western majority of WV is still fighting the war between the states, politically speaking.
I'm less than a mile as the crow flies from both the WV and PA state lines and if a D/R "civil war" ever does break out, I'm screwed.
