"I think the President's speech was extremely well- received by American people. We're not as interested so much in what the pundit gallery has to say... Some pundits have said good things about the president's speech," David Plouffe, senior advisor to Obama said in an interview.

"We thought the President's speech met the American people exactly where they're living. You know, tell us where we are and how do we move forward with a middle class economic strategy that's really going to grow the economy and enhance middle class security," he said.

But, he said that the Democratic convention is unlikely to see any major bounce for Obama.

"This is a close race... so you're not going to see - well, you're not going to see huge swings. I think we definitely are going to help ourselves in terms of turnout. I think Obama supporters are very energised. I think independent voters, what they saw from the President, from President Clinton, and other speakers was a plan to move forward," Plouffe said. u00a0
