Check out commentary from the following pollsters.
Gallup:
No Sign That Obama's Overall Job Approval Rating Has Been Significantly Affected
The trend data show a four-point increase in approval of Obama's handling of the oil spill between Gallup's June 5-6 poll and the June 19-20 poll. These results suggest a possibly slight benefit to Obama from his recent visits to the Gulf region, culminating in his nationally televised address from the Oval Office last Tuesday.
There is less evidence that the oil spill has affected Obama's standing in the public's eye from a comparison of his weekly overall job approval average before the BP spill on April 20 with his average after the spill. Obama's ratings have been slightly lower in the last four weeks than they were in the four weeks prior to that, but his average in either time period is not much different from his 48% average in the four weeks immediately prior to the spill.
Pew:
Obama's Ratings Little Affected by Recent Turmoil
Since the beginning of this year, President Obama has signed a controversial health care measure, coped with a stubbornly high jobless rate, and struggled to manage the largest environmental disaster in the nation’s history. In that period, Obama’s overall job approval rating has moved from 49% to 48%.
So, logically what conclusion would you draw?
As Brendan Nyhan at pollster.com writes (he gives a few examples from MSNBC, whose latest poll is driving the current narrative):
The narrative that President Obama's approval ratings are being heavily damaged by the oil spill in the Gulf of Mexico is quickly overwhelming the critical faculties of the media.

If you ever wondered why bloggers blog, you're looking at it. You can't leave something as important as facts to the media. And the media really need to read something other than their own polls.
