Four in 10 registered voters approve of President Obama's handling of the economy, a new poll found.

According to the McClatchy-Marist Poll, released Thursday, 57 percent disapprove and the remaining 3 percent are unsure.

The 40 percent approval rating marks a record low for the McClatchy-Marist poll. The previous low came in September, when only 41 percent approved of Obama's handling of the economy.

“These economic numbers could spell trouble for President Obama's reelection prospects,” said Lee M. Miringoff, director of the Marist College Institute for Public Opinion. “Oddly, though, he still isn't being faulted for the sluggish economy. Most think it was there waiting for him when he took office.”

The poll found 71 percent of Democrats surveyed approve and 27 percent disapprove. That’s a substantial uptick since January, when 15 percent of Democrats disapproved.

Meanwhile, just 11 percent of Republicans approve of Obama's performance on the economy, while 87 percent do not. The poll found in January that 7 percent approved and 88 percent disapproved.

The findings come the same day first-quarter growth numbers for the U.S. economy were released. The Commerce Department said economic growth had increased at a sluggish 1.8 percent.
