Two important notes:
1. These numbers come from two of the most important members of Obama's Media Support Team, i.e., CBS and the New York Times.
2. This poll included all adults, including adults who are unlikely to vote. Polls that include adults who are not expected to vote tend to skew favorably for Democrats.
With those caveats, Obama's bad news is probably even worse than it would appear at first glance:
"Obama’s approval rating has slipped to 43% - his lowest so far - while his disapproval rating has reached an all-time high in this poll of 50%..."
The hope came early, finally comes the change. Even apart from his job performance, Americans don't like Obama anymore:
"And for the first time, more Americans have an unfavorable opinion of Barack Obama than a favorable one..."
The unfavorable opinion has surged to its current high from only 34% in January.
UPDATE: Some train wrecks are fun to watch!
