CHARLOTTE, the United States - US President Barack Obama on Thursday night formally accepted the Democratic Party's presidential nomination for a second term, offering his own "harder but better path" to rejuvenate support just two months ahead of the November election.

During the prime time speech at the Democratic National Convention, Obama stressed that under his first term the nation is "moving forward."

"I won't pretend the path I'm offering is quick or easy. I never have. You did not elect me to tell you what you wanted to hear. You elected me to tell you the truth. And the truth is, it will take more than a few years for us to solve challenges that have built up over decades," said Obama.

Obama took the stage Thursday night after his running mate Vice President Joe Biden who asked for four more years to complete "a mission we will complete."

Organizers of the convention said nearly 6,000 delegates have attended the three-day convention in Charlotte, the largest city of North Carolina.

Democrats hope the three-day convention would generate a renewed enthusiasm for Obama's re-election bid and help him win the battleground of North Carolina.
