Given that the first flurry of state polls were 'Friday centric' and the companies were somewhat more sympathetic traditionally to Romney it is possible the 'bounce' was in fact minimal. Obama was leading in many states by a larger amount than a swing of even 2% to Romney could damage which make the Ohio polls and Florida poll look off; we still need to get polls from those states to give us a clearer picture.
To quote myself:
It's important to remember that regardless what lead Obama has had during the campaign whether it's level with Romney, up 2 points or up 5 he has always outperformed Romney in the swing states. His national lead may have bounced up and down in August/September but didn't really affect his lead in states like Ohio which had been scarily constant. His electoral college numbers also remained constant. When Rasmussen had him down 2 points to Romney last month he still performed well in the state polls.
However we've had some interesting post debate polls that suggest his lead in Florida and Virginia have been eliminated and in danger in Ohio. Those would be worrying signs, but they are 'snapshot' polls so we need more out of these states to be sure.
