Told y'all
Yes you did, but you're still not (and won't be) right, LOL. The often-labeled "Working Class Whites" are going to have to deal with the business community, wealthy White college graduates, suburbanites who don't care that much about social issues and whatever other boogeymen you fancy for quite a while.
Except the "White Working Class" will be GOP and all of the other groups you mentioned will be largely Democratic constituencies within the next 10 to 30 years.
How could the GOP win elections if the only people consistently voting for it were the white working class?
