The left-liberal mag. The American Prospect, in the last few issues has had an intersting debate between the DLC poobahs, Al From and Stanley Greenberg and Ruy Teixiera from CAF. See their website. http://www.prospect.org/
Greenberg, btw, just got back from Italy, having been the pollster for the opponent to Berlosconi. Yrs. ago, when he taught poli sci, he wrote a neo-marxist work, "Race, State and Class in Capitalist Development." Comparison, if memory serves fom the review in Kapitalistate at the time, of Apartheid south Africa and the US Deep South. Cf. George Frederikson on same.
