Mitt Romney and the Republican National Committee, "Who will raise taxes?"

What it says: “According to an independent, nonpartisan study, Barack Obama and the liberals will raise taxes on the middle class by $4,000.”

What it means: After a debate in which middle-class taxes played a major role, Mitt Romney is pressing his advantage in hopes of changing polls that show voters think he will favor the rich.

Factchecker: Three Pinocchios. "The study shows how much lower taxes could be if the nation did not keep adding to the debt load; it does not show, as the ad claims, that Obama has some sort of secret plan to raise taxes."

Who will see it: The RNC and Romney campaign together just bought $1,705,360 of time in Ohio and $1,774,630 in Florida.
