Looks like it's not happening this time either. In fact, I guess this would be the first presidential election since 1972 in which neither ticket includes a southerner....assuming you don't count Maryland (or Delaware, since, as Joe Biden reminds us, it "was a slave state").
Actually, if you *do* count Maryland as the South, but not Delaware, then this is the first election without a southerner on either ticket since....what? 1944?
I'd say 1940, because by that logic, Missouri is just as much a Southern state as Delaware or Maryland.
