But that's what the internals of the latest Gallup poll tell us. Prior to the Republican convention, Kerry had a one point lead among RVs (47-46) in the battleground states. After the Republican convention, now that battleground voters have had a chance to take a closer look at what Bush and his party really stand for, Kerry leads by 5 in these same states (50-45)! Note that Kerry gained three points among battleground voters, while Bush actually got a negative one point bounce.

And wait--there's more! The Gallup poll's internals also show that Kerry continues to lead among independents (49-46) and that both parties' partisans are equally polarized for their respective candidates (90-7). Note that these findings directly contradict the results of the recent Newsweek poll, which showed Bush doing much better among Republican partisans than Kerry was doing among Democratic partisans. Note also that, given the equal polarization of partisans and Kerry's lead among independents, the only possible reason Bush has any lead at all among Gallup's RVs must be because their sample has a GOP advantage on party ID (my guess is 5 points) that is inconsistent with almost all other polling data from this campaign season.
