Campaigns don't release their internal polling. However, one can get a glimpse as to what those polls are saying by looking at the $$ spent by each campaign. Obama has spent over 5 million in campaign ads alone in Florida since the beginning of June thru July 27th. McCain has spent ZERO.
That should tell you all you need to know.
Maybe the RNC is running some ads.
Just pay attention to the small print next time you see them (assuming you can see it - sometimes my TV cuts a little bit of the bottom off and you can't really read it).
