Feingold '08
Kathryn Jean Lopez over at National Review overreads the results of Lamont v. Lieberman to declare that in a Democratic party completely overrun with, as an anonymous Republican she quotes puts it, "Kossacks, Cindy Sheehan disciples, and Big Labor special interests who are increasingly devoted to a cause-oriented political jihad against what they view as a Democrat Establishment" that 2008's presidential nomination is Russ Feingold's to lose.
For a more moderate read on what Lamont's primary victory portends, one less certain that it marks the final victory of the mad antiwarmonger, see my interviews with two Democrat pundits John Nichols and Mark Schmitt here.
