A new study by Vanderbilt University found that an ad from Mitt Romney criticizing President Obama over a super-PAC attack that insinuated the presumptive Republican nominee was responsible for the death of a cancer patient is having a measurable effect on swing voters.
The study found that Romney's "America Deserves Better" commercial was resonating with swing voters, moving "pure independents" who remained undecided some 6 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.
"It was the first time among all the ads we have studied where a Romney attack moves down the president's numbers among pure independents," he continued.
