Rasmussen Reports has a daily tracking poll which shows that Obama's overall Approval Rating has dropped from 30 to -2. The Approval Rating (blue line) is the difference between the percentage of respondents who Strongly Approve and the percentage who Strongly Disapprove of the job he is doing as President.
Note that the main reason his approval rating has dropped is that the number of people strongly disapproving of his performance has risen significantly. His star appeal has waned somewhat, but the bigger story is that more and more people feel pretty strongly that he is not doing a good job.
I view this as a positive for the outlook, since it means that his ability to continue pushing a radical left-wing agenda is diminishing daily.
In Spanish there is a saying which describes this: El que mucho abarca, poco aprieta. It's not easy to translate, but it goes something like this: "He who tries to take on a lot ends up not doing very much." In a word, it would be "overreach."
