Most of the Democrats he’s attracting seem to be middle class/educated suburbanites who are fiscally conservative/socially moderate and have voted Democrat in recent years because they view the GOP as having been taken over by the Huckabee/big govt types, as well as independents who defected to the Dems in 2006 because of Abramoff&Iraq.
When one tries to classify, categorize, and label, one has to generalize. In my previous post I made the classification of left and right against the middle. You can also make the classification based on Populism versus Elitism.
The modern GOP has been a coalition between the cultural populists and economic elitists while the modern democratic party has been a coalition between cultural elitists and economic populists. Within both parties, the populists are dis-satisfied with the elitists. And Ron Paul is trying unify the nationalist populists against the global elitists, trying to dovetail with paleo-cons versus the neo-cons.
