WASHINGTON — President Barack Obama still has the approval of a majority of Americans, but it's an increasingly pessimistic nation.

The public grew slightly more dispirited on a range of matters over the past month, including war and the economy, continuing the slippage that has occurred since Obama took office, the latest Associated Press-GfK poll shows.

This comes at a time when he is trying to revive the struggling economy, considering sending more troops to the 8-year-old Afghanistan war, muscling a health care reform overhaul through Congress and hoping to push through other ambitious measures like legislation focused on climate change.

People were gloomier about the direction of the country than in October. They disapproved of Obama's handling of the economy a bit more than before. And, perhaps most striking for the commander in chief, more people have lost confidence in Obama on Iraq and Afghanistan over the last month. Overall, there's a malaise about the state of the nation.

"It's in pretty bad shape," said truck driver Floyd Hacker of Granby, Mo., a Democrat who voted for Obama. "He sounded like somebody who could make things happen. I still think he can."

Still, Hacker said, he questions the president's approach to the economy, what the U.S. is trying to accomplish in Afghanistan and Obama's focus on health care, adding, "He can't handle everything at one time."

Public attitudes like that are troubling for a president trying to accomplish an ambitious agenda at home while fighting wars abroad, as well as for a Democratic Party heading into a critical election year. It will have to stave off losses that a new president typically experiences in his first midterm elections. A third of the Senate, all of the House and most governors' offices will be on the ballot.

The findings underscore just how quickly the political environment can change, a lesson for out-of-power Republicans who are buzzing with energy after booting Democrats from rule in Virginia and New Jersey governors' races last week.

It was just over a year ago that Obama won the White House in an electoral landslide and Democrats padded their congressional majorities. The country was riding high with optimism by just about all measures when Obama took office in January.

Hope and change were in vogue back then. But change didn't happen overnight, as the rhetoric of campaigning crashed headlong into the realities of governing. And hope slipped in a country that always has clung to it.
