Thank you for the wonderful questions!
1. Democratic strength in the Dakotas remains based in the east, though it has steadily expanded. Eastern Idaho is strong for Republicans, but their strength with Mormons is falling with each cycle. Utah is trending D.
2. In New York and Pennsylvania eh? I may make county maps. In Pennsylvania the Scranton and Pittsburg areas are very strong for the Democrats, though Al Gore did better than Glenn in the Philadelphia suburbs in 1988. Philadelphia is a Republican stronghold by now. New York City has been steadily trending R. The high population areas Gore is improving in are primarily suburban, generally due to his right-Third Way economics and foreign policy wins.
