President Obama's job approval rating has dropped to a new low of 40 percent, according to the Gallup daily tracking poll.

The White House has worked double-time to get Americans to agree with their assertion that Republicans are to blame for the current debt ceiling impasse, but this new number shows the message doesn't seem to be resonating. Congress - and leaders John Boehner and Harry Reid - aren't getting good marks either.

As recently as the beginning of June, President Obama's approval was at 50 percent. It has been consistently falling since mid-July.

Perhaps a more telling number is Obama's falling favor amongst independents. Only 34 percent approve of the job he is doing. That's down 7 percent from three weeks ago.
