When the Moral Majority crumbles and the GOP becomes more Romneyesque, yes.
How would Democrats counter? Would we go for the South again?
If I were to guess the Democrats would revert back to being the anti-elitist party and start portraying the Republicans as the party of grey poupon.
I love that 80s commerical. "Pardon me. Would you pass the Grey Poupon.... But of course." Funny how in 80s sitcoms Republicans were perceived as "the Prep school kid from Connecticut." Now CT is one of the most Democratic states in the nation. I think the Democrats can still go with more populist policies and win some older, inner suburbs. Philly area I'm thinking Jenkintown, Conshochocken, etc. GOP was still winning some of the more exurban/rural parts of Montco and Bucks even up till 2004.
