You mean back when Americans of all ages voted along class lines (somewhat) and working class people couldn't attend universities unless they'd had a military career before?
Of course, there were plenty of elite Democrats back then ("before the 70s" is an awfully long time), and there have always been certain working-class areas that voted heavily Republican (some since the Civil War era)....
What are some working-class areas that were Republican in the 30's-40's era?
Also:
SW/South-Central Missouri(this area went solidly Landon in '36)
NE Kansas
Upstate NY, Northern PA, Vermont, NH, Maine, E. Massachusetts
A large chunk of rural Michigan, especially on the West End and the "thumb" (or maybe it's called the finger
DRIFTLESS AREA, particularly the section in Illinois, which is one of the few rural areas Dems do well in now.
