From Eric Dondero:

Yesterday, as the news was breaking about the Dow plummeting over 400 points, the new daily averages for Gallup and Rasmussen were released. Gallup had Obama at -10 (41% approval, 51% dissaproval), and Rasmussen -9 (45%, 54%).

That brought Obama down to the very lowest culmultative Approval rating ever posted at RCP, right at 44.0%. The previous low was 44.2% back in December of 2010.

Though, his Disapproval rating is not the highest it's ever been. Now at 50.2%; the previous high was 50.6%.

He's also trending dangerously close to the psychologically important, below 40% level on approvals in Gallup.
