Here are three excellent articles on the recent Iowa caucus:
1. Why the absence of George Allen (remember him?) in the Republican presidential campaign caused Romney, Giuliani, McCain, and Thompson to shift to the right on social issues, opening the door for a genuine evangelical (Mike Huckabee) to win in Iowa.
2. How the Obama campaign marks the emergence of a new generation of political activists, in the way that 1960, 1980, and 1992 did.
3. How both Huckabee (and Obama) represent drastic new shifts for their parties, with Huckabee especially represented the "new evangelical" who is pro-environment, populist, anti-war, and not a cultural warrior.
