The latest Pew poll shows that Mitt Romney’s net unfavorability is 16 points (34 percent favorable ratings verse 50 percent unfavorable), while Barack Obama’s net favorability is 9 points (42 percent unfavorable verse 51 percent favorable). Yes, the polling sample is skewed with an 11-point advantage for Democrats (those interviewed included 22 percent Republicans and 33 percent Democrats). Although, for whatever it’s worth, when this poll was done in June, Democrats had a 9-point advantage, and Romney’s net unfavorability was only 9 points at that time. Even taken into account that the sample isn’t representative, it still looks like Romney’s unfavorables are increasing.
