President Obama's approval rating has hit a new low, according to a third pollster.

The Quinnipiac University poll shows just 39 percent of Americans now approve of Obama's job performance, compared with 54 percent who disapprove.

The drop in Obama's fortunes appears directly tied to the rough rollout of his health care law, which has become significantly more unpopular since the Obamacare exchanges Web site went live on Oct. 1.
