Pennsylvania in 20 years?
Delaware county more Dem than Montco? No. Northampton couny Dem? No. I don't see Centre county becoming Dem either.
Phil...like any silly prediction map nothing is set in stone and everything depends on the candidate. But here we go...
Montco isn't going to grow much more then it already is, from all the restrictions they are putting on growth. Maybe Montco should be dark like Delaware county, which will continue to see a lot of spillover from Philadelphia.
And I think Northampton and Lehigh will stay just barely in the Democratic column. I know "CONSERVATISM IS ON THE RISE!!!11!!" like you say, and they could go Republican with a moderate...but the Philly and New York suburban effect will eventually take over, and probably already is beginning to.
Centre county's college population will continue to grow and combined with some of the boroughs that are Democratic strongholds, they may just outvote the Republican areas. Hell, they almost did in 2004.
In 20 years, the only SW PA county that might be Dem besides Allegheny will be Fayette, maybe.
