Edit: Yes, I do realize that Corporate Right, Libertarian Right and Fiscally Conservative aren't exactly the same thing. They do overlap considerably, espeically when talking about their base, which is usually middle, upper middle and upper class income levels and more highly educated people. The constant overtures to the Social Conservatism and let downs for these three groups since the 1990's, means that this demographic has been leaving for the Democrats. Without them in primaries, poorer, less educated populists will gain more influence in the primaries creating a self-fulling prophecy of socially conservative, big gov't populism
Umm....aren't a good number of Religious Right types (especially younger ones, relatively speaking) solidly middle to upper middle class in both income and education levels?
I do agree that the poorer members of this demographic are more likely to be populist on issues like economics, trade, and the role of the federal government. But that's to be expected, no? (Think of the difference between a poor rural Southern Baptist from Texas and a wealthier counterpart from the Dallas or Houston suburbs).
