Via Gallup:
President Barack Obama remains highly popular among the U.S. public at the end of his first month in office. However, the 63% of Americans currently approving of his job performance is down slightly from his initial 68% rating in January. The percentage disapproving has doubled, from 12% to 24%.

Increased public disapproval of Obama over the past month is mainly offset by a decrease in the percentage of Americans saying they have no opinion of his job performance. The latest figures are based on Gallup Poll Daily tracking from Feb. 19-21.
While Obama’s initial 68% job approval rating was one of the highest in Gallup polling history (from Dwight Eisenhower through George W. Bush), his current 63% job approval rating is typical of how the last several presidents have fared at the one-month mark.

According to Gallup polling on all elected presidents from Richard Nixon through George W. Bush (this excludes Gerald Ford, who assumed office after Nixon resigned), the range of job approval for new presidents after about a month in office extends from 55% for Ronald Reagan to 71% for Jimmy Carter. The average one-month approval rating for all six past presidents is 62% — nearly identical to Obama’s current 63%.
As Matthew Yglesias points out, rather than a broad decline in approval, the interesting part is the microfoundations of the movement: Modest increases in the esteem in which Obama is held by Democrats and independents. Obama´s decisions since to pulling the public in a more polarized direction.
Obama has lost no support from Democrats and independents since taking office, but his approval rating from Republicans has dropped steadily week by week, from 41% at the start of his term to just 30% today.
