New Polling: Obama's Approval Slides

President Obama's approval rating is going down, according to CBS News--both in general, and on the war in Afghanistan. His overall approval/disapproval slipped from 56/43 percent last month to 53/36 percent this month ('s major poll average puts him at 51.2 percent).

More specifically, it looks like the long decision-making process on Afghanistan strategy has taken its toll: only 38 percent approve of how he's handling the war, while 43 percent disapprove. Last month, CBS had that figure at 42/34 in favor of Obama. CNN reported a much bleaker 42/56 split two weeks ago, but what's significant about the CBS numbers is the directionality--his approval rating is going down with time.
