[rabbitproof]

So, when were those surveys fielded?

More importantly, if people think Obama's ads are more negative, why are the polls swinging for Obama? Are respondents unconsciously calling the ads effective? Or are they agreeing with the "more negative" ads?

Thanks for posting but I still doubt a ~20% margin in perceived negative ads (fielded over who knows when and with what margin of error) is driving the momentum shift more so than the heavy economic news that's come out in the last 3-4 days.
