Support for President Obama's economic stimulus package has slipped since January, while Obama himself enjoys favorable impressions among Americans, according to a new survey from the Pew Research Center.

According to the study, 51 percent of Americans think the stimulus package is a "good idea," compared to 57 percent in a similar survey published in early January.

But as Obama has gone on a media blitz in support of the package, he enjoys high ratings on favorable attributes: 92 percent view him as a good communicator, 87 percent see him as warm and friendly, and 66 percent view the president as bringing a "new approach to politics," according to Pew.

Pew surveyed 1,303 Americans Feb. 4-8 for the poll.
