President Barack Obama's re-election glow is gone. Congress' reputation remains dismal. And only about one in five Americans say they trust the government to do what's right most of the time, an Associated Press-GfK poll finds.

Obama's overall job approval rating is at its lowest point since his re-election: 50 percent, with 47 percent disapproving. His approval rating among opposition Republicans _ 10 percent _ is back to where it was before the election. Among independents, disapproval has crept up to 49 percent.

Most adults disapprove of Obama's handling of the federal deficit, a festering national problem. But they also dislike key proposals to reduce deficit spending, including a slower growth in pensions for the elderly and changes to health care programs.

Rounding out the portrait of a nation in a funk, the share of people saying the United States is heading in the wrong direction is at its highest since last August: 56 percent.

Just 7 percent of Americans say they trust the government in Washington to do what is right “just about always,” the AP-GfK poll found. Fourteen percent say they trust it “most” of the time. Two-thirds trust the federal government only some of the time; 11 percent say they never do.

Ratings of the president's handling of the economy are back in negative territory, with 52 percent disapproving and 46 percent approving. In last September's run-up to the election, 49 percent said they approved, and 48 percent disapproved.

In the new poll, disapproval among independents on handling the economy is up 10 percentage points since September 2012. It now stands at 57 percent.

Fifty-six percent of Americans disapprove of the way Obama is handling the federal deficit, while 39 percent approve. Those levels have changed little in the past 15 months.

Americans are ambivalent about raising taxes on wealthier households, which Obama proposes as a means to help shrink the deficit. Forty-five percent support new limits on itemized tax deductions for the top 2 percent of earners. That covers individuals making at least $183,000 a year, and married couples making $223,000 or more. One in three Americans oppose the idea.

Most Democrats _ 57 percent _favor the proposal. But only 41 percent of independents and 33 percent of Republicans do.

Most Americans support Obama's proposal that would require those making $1 million or more annually to pay at least 30 percent of their earnings in federal income taxes. Just under 60 percent support the idea, while 29 percent oppose it.

Democrats might find comfort in the fact that Republican lawmakers are even less popular than Democrats.

The Associated Press-GfK Poll was conducted April 11-15, 2013, by GfK Roper Public Affairs and Corporate Communications. It involved landline and cell phone interviews with 1,004 adults nationwide. Results for the full sample have a margin of sampling error of plus or minus 3.9 percentage points; it is larger for subgroups. (AP)
