Iowa, Florida, Pennsylvania, Virginia all came in at 46% approval, Nevada, New Mexico, and North Carolina all reported 45% approval, Ohio reported 44%, and Colorado and New Hampshire reported 43%. Gallup says:
The 50% approval mark is significant because post-World War II incumbent presidents who have been above 50% job approval on Election Day were easily re-elected. Presidents with approval ratings below 50% have more uncertain re-election prospects.
From January to June of this year, Gallup asked more than 90,000 U.S. adults whether they approved or disapproved of the job Obama is doing as president. Nationwide, 46% of Americans approved and 46% disapproved during this time.
