WASHINGTON -- President Barack Obama confronts a daunting array of domestic and foreign policy challenges as he begins a second term amid a political climate so fractured that compromise has become all but impossible.

The country is not in economic freefall as it was when he was first elected. The war in Afghanistan is winding down. The U.S. role in Iraq is finished.

The country has stubbornly high unemployment. Depressed incomes. High gasoline prices. The government owes $14 trillion and the debt is climbing. The federal budget is a mess of temporary measures held together by short-term fixes always about to expire and plunge the government into crisis and the economy back into recession. There are fewer Americans on the battlefield in Afghanistan and Iraq and Osama bin Laden is dead, but al Qaida remains a threat, new governments in the Middle East may or may not be on America’s side, and Iran still threatens to bedevil the U.S.

As Obama looks out on this second term, he also faces a different political landscape than the one that greeted him four years ago. Then, he swept easily into office on a wave of hope and optimism. Now, he had to struggle to convince the country to rehire him, and he must navigate a political system that, if possible, is even more polarized. This Congress, with an approval rating hovering around 11 percent, has been mocked as the least productive in six decades.

Obama immediately called congressional leaders to talk about the legislative agenda for the remainder of the year. In his acceptance speech early Wednesday, he pledged to work with members of both parties in his second term.

“In the coming weeks and months, I am looking forward to reaching out and working with leaders of both parties to meet the challenges we can only solve together: reducing our deficit; reforming our tax code; fixing our immigration system; freeing ourselves from foreign oil,” he said. “We have more work to do.”

But Senate Minority Leader Mitch McConnell, R-Ky. said in a statement that Obama must propose policies that will be acceptable to both parties.

“Now it’s time for the president to propose solutions that actually have a chance of passing the Republican-controlled House of Representatives and a closely divided Senate, step up to the plate on the challenges of the moment, and deliver in a way that he did not in his first four years in office,” McConnell said. “To the extent he wants to move to the political center, which is where the work gets done in a divided government, we’ll be there to meet him halfway.”

A political loner who has developed few relationships with lawmakers, Obama must try to forge agreements on major issues with Republicans who almost unanimously opposed his agenda in the first term and with Democrats who are looking for him to deliver on promises, such as climate change legislation, that he abandoned in his first term.

“The major challenge for any president is to build a consensus in the country and not just in Washington,” said Ken Duberstein, chief of staff for President Ronald Reagan. “You have to build coalitions to win. Every presidency ultimately goes into a ditch, somehow and for some reason, and you have to have not only the people’s trust but the members of Congress know you and trust you. That has not yet developed.”
