Study: Romney criticism of Obama's cancer ad effective with swing voters

The study found that Romney’s “America Deserves Better” commercial was resonating with swing voters, moving “pure independents” who remained undecided some six percentage points in the Republican’s favor.

The researchers said this was the first ad of the campaign cycle they had studied that resonated with true swing voters.

“What is new here is that the ‘America Deserves Better’ ad seems to score points for Romney,” Ad Rating Project leader and Vanderbilt political science Professor John Geer told UPI.
