Accepting the nomination as the Democratic candidate for the White Hous and speaking on the last night of the Democratic National Convention, U.S. President Barack Obama asked voters for patience in rebuilding the economy.
President Barack Obama delivered a scaled-back pitch for another term in steering clear of ambitious promises and warning voters that the next four years could hold disappointment even if he won.
It was a sharp contrast to the speech Obama delivered four years ago in Denver, when he emerged as a transformative candidate, the first African-American to win the presidential nomination of a major party.
"I won't pretend the path I'm offering is quick or easy," Obama said. "It will take more than a few years for us to solve challenges that have built up over decades."
Although Obama has won significant victories in office, from a dramatic expansion of health coverage to the end of the Iraq war, voters remain preoccupied with the sluggish economy. Obama's own aides have struggled to make the case that voters are better off now than they were four years ago, and the president could be hurt by a gap between expectations and reality.
Romney is hoping to win over disillusioned Obama supporters who still hold a favorable view of the president even as they give the economy low marks.
Obama, by contrast, seemed to be aiming squarely at core supporters in a speech that thrilled the 20,000 Democratic stalwarts in Charlotte.
He celebrated signature accomplishments such as the auto-industry bailout and the death of Osama bin Laden, and delivered red-meat attacks on Romney that analysts said would go a long way toward firing up those who backed him four years ago.
