If you go to the RCP site and take a look at the polling averages since the RNC, you will see a 5-10 drop in McCain support and Oama has gained 5-10% in every one of these states except Nevada and Indiana. ANd in those two states, while McCain has been steady, Obama has been gaining to a near tie over the month of September. The decline is almost assuredly related to Palin opening her mouth and McCain's erraticism on the Bailout.
