Obama advisors don't expect big bounce in polls

CHARLOTTE, N.C. (AP) - President Barack Obama is expected to lay out his vision for a second term, even as advisers say they don't anticipate a big bounce in the polls following the Democratic National Convention.

White House senior adviser David Plouffe tells ABC's "Good Morning America" he expects the race to remain "tight as a tick" until Election Day.

Plouffe says Americans will have a clear sense of where Obama thinks the country should go after his speech Thursday night.

Obama campaign advisor David Axelrod says he was thrilled with former President Bill Clinton's speech, which laid out the convention's most forceful case so far for re-electing Obama.

Axelrod tells NBC's "Today" he's not worried about Clinton upstaging Obama. He says Clinton played the role Democrats wanted him to play.
