Susan French, a Democrat who watched the speech in Cincinnati, Ohio, said she was impressed by how forceful Obama was, though she thought the speech could still leave him open to attack.
"He did a great job addressing the areas where he has been attacked: patriotism, his qualifications for the job and how he plans to pay for all his ideas," she said.
"The over-the-top stadium show (surrounding the speech) might help motivate his supporters but it might be playing into the hands of his critics who try to paint him as a rock star with no substance," she said.
But to many Republicans, the speech merely amplified many of their concerns about the candidate who, at 47, would be one of America's youngest presidents if elected on Nov. 4.
"He described a chance to keep the American promise and he made a lot of promises. He is the pied piper of promises," said Mike Vanderboegh, of Pinson, Alabama.
"A government that is powerful enough to give you everything you want can take everything you have," he said, adding, "He is scarier than (former President Bill) Clinton because he is arrogant and a true believer."
FEEL-GOOD SPEECH
Bob Lindsey, a business owner in Birmingham, Alabama, picked up on a frequent criticism of Obama -- that little lies behind the candidate's capacity to spin fine words.
