Due largely to the low marks he received for his handling of the economy and health care, and his drop in support among independents, a new Quinnipiac survey finds President Obama's approval rating down to 50% -- his lowest since becoming president (July 27- Aug. 3, 2409 RV, MoE +/- 2%).

Obama's approval rating includes 85% of Democrats and 16% of Republicans, while independents are split 45%-45%. He now has a 53.6% RCP Average Job Approval Rating.
