EDWARDS CASTS HIMSELF AS RESPONDER-IN-CHIEF TONIGHT. After President Bush addresses the nation about Iraq tonight at 9 p.m., flip to MSNBC, where John Edwards has purchased air time to, according to a campaign email, "challenge the President's remarks with a strong call to the nation to end the war now." Seems like a smart strategy for the candidate fighting for second place, and probably a way the campaign hopes to steal away some of Barack Obama's antiwar thunder. Obama had a great line in his Iraq speech yesterday: "I opposed the war in 2002. I opposed it in 2003. I opposed it in 2004. I opposed it in 2005. I opposed it in 2006." --Dana Goldstein
