More Americans believe Barack Obama’s attacks on Mitt Romney are unfair, than think the Republican nominee is wrongly attacking the president, a new survey shows. The USA Today/Gallup poll found that 44 percent of all Americans say Obama has been attacking Romney unfairly during the campaign compared to 40 percent who think the wrong comes from the GOP's man.The findings show that on both sides there is an increasing perception that candidates are being unfairly attacked, with 38 percent of Americans last month saying Obama’s attacks were unfair vs. 36 percent for Romney.Two-thirds of Republicans and close to half of independents (46 percent) are now saying the president’s attacks on Romney are unfair, up from 59 percent and 38 percent, respectively.Independents have grown more critical of Obama's behavior than of Romney's, with about half of independents now perceiving Romney being attacked, the poll indicated.In fact, Romney’s ad that hits back at an Obama attack ad insinuating that he was responsible for the death of a cancer patient is driving down Obama’s numbers among independents for the first time in the campaign ad cycle, The Hill reported. Romney's "America Deserves Better" ad moved "pure independents" who remained undecided some 6 percentage points in Romney’s favor, a new study by Vanderbilt University found.
