Sarah Palin has hit upon a crowd-pleasing anti-Obama one-liner, which she delivered this way Friday night in Salina: "We need a commander in chief, not a professor of constitutional law." Among Republicans, this is a talking point aimed at fortifying the party's national security credentials in time for the 2010 congressional elections. But when did knowing and respecting the Constitution become a bad thing? Plus, many of the politicians criticizing the Obama administration for its handling of attempted underwear bomber Umar Farouk Abdulmutallab are "unknowing of the facts, and they're making charges and allegations that are not anchored in reality," deputy national security adviser John Brennan (in photo) said Sunday on NBC's "Meet the Press." Brennan, who headed the National Counterterrorism Center under President Bush, made the point that the FBI guidelines used in dealing with the Abdulmutallab were put in place under Bush. "I'm just very concerned, on the behalf of the counterterrorism professionals throughout our government, that politicians continue to make this a political football and are using it for whatever political or partisan purposes, whether they be Democrats or Republicans. In the last administration, Democrats I felt were speaking incorrectly about the progress that we were making on the terrorism front. The same thing is true today. And I think those counterterrorism professionals deserve the support of our Congress."
