CHARLOTTE, N.C. -- His re-election in question, President Barack Obama conceded only halting progress Thursday night toward fixing the nation's stubborn economic woes but vowed in a Democratic National Convention finale, "Our problems can be solved, our challenges can be met."
"Yes, our path is harder -- but it leads to a better place," he declared in a prime-time speech to convention delegates and the nation, blending resolve about rescuing the nation from near economic catastrophe with stinging criticism of Republican rival Mitt Romney's own proposals.
Widely viewed as reserved, even aloof, Obama acknowledged "my own failings" as he asked for a second term, four years after taking office as the nation's first black president.
Citing progress toward recovery, he said, "After a decade that was defined by what we bought and borrowed, we're getting back to basics and doing what America has always done best: We're making things again."
Obama's speech was the final act of a pair of highly scripted national political conventions in as many weeks, and the opening salvo of a two-month drive toward Election Day that pits Obama against Romney, the former governor of Massachusetts.
Vice President Joe Biden preceded Obama at the convention podium and proclaimed, "America has turned the corner" after experiencing the worst economic crisis since the Great Depression.
Obama didn't go that far in his own remarks, but he said firmly, "We are not going back, we are moving forward, America."
With unemployment at 8.3 percent, the president said the task of recovering from the economic disaster of 2008 is exceeded in American history only by the challenge Franklin Delano Roosevelt faced when he took office in 1933.
"It will require common effort, shared responsibility and the kind of bold persistent experimentation" that FDR employed, Obama said.
In an appeal to independent voters who might be considering a vote for Romney, he added that those who carry on Roosevelt's legacy "should remember that not every problem can be remedied with another government program or dictate from Washington.
He said, "The truth is, it will take more than a few years for us to solve challenges that have built up over the decades."
