CBS News Poll analysis by the CBS News Polling Unit: Sarah Dutton, Jennifer De Pinto, Fred Backus and Anthony Salvanto.
Last week, President Obama signed historic health care reform legislation into law -- but his legislative success doesn't seem to have helped his image with the American public.
The latest CBS News Poll, conducted between March 29 and April 1, found Americans unhappier than ever with Mr. Obama's handling of health care - and still worried about the state of the economy.
President Obama's overall job approval rating has fallen to an all-time low of 44 percent, down five points from late March, just before the health bill's passage in the House of Representatives. It's down 24 points since his all-time high last April. Forty-one percent of those polled said they disapproved of the president's performance.
More results from this CBS News Poll will be released in Friday's broadcast of the Evening News with Katie Couric, which airs at 6:30 p.m. Eastern.
When it comes to health care, the President's approval rating is even lower -- and is also a new all-time low. Only 34 percent approved, while 55 percent said they disapproved.
Americans are still worried about the economy, with 84 percent telling CBS they thought it was still in bad condition. However, even that high number represents an improvement: nine in ten thought the economy was bad during the last half of 2008 and at the beginning of 2009, when Mr. Obama assumed the Presidency.
Concern about job loss remains high; slightly more Americans now (35 percent) than in February (31 percent) were "very concerned" that someone in their household would lose a job. Nearly six in ten Americans said they were at least "somewhat concerned" about a job loss.
As has often been the case, lower-income Americans tend to be the most concerned about job loss.
This concern is reflected in yet another low approval rating -- this time for the President's handling of the economy. Just 42 percent said they approved of how President Obama is handling the economy, only one point above January's all-time low. Half of the public disapproves.
