(Newsroom America) -- Eight in 10 voters in the nation's dozen or so swing states have seen campaign ads by either President Barack Obama or GOP nominee Mitt Romney so far, compared with about six in 10 in non-swing states, a Gallup survey released Monday said.
The results of the survey are the clearest indication yet that the two candidates are putting most of their time, money and effort into reaching voters in about a fourth of the nation - the states that will decide whether Obama gets another term or whether Romney will get his shot to lead the nation.
Despite the heavy saturation of campaign ads in those key states, however, "at the same time, swing-state voters are no more likely than non-swing-state voters to say they have been contacted by one of the campaigns or to have been an active participant in the campaign," the survey said.
That indicates the respective campaigns, so far, are letting their campaign ads do most of their talking.
The poll was conducted among voters in Colorado, Florida, Iowa, Michigan, Nevada, New Hampshire, New Mexico, North Carolina, Ohio, Pennsylvania, Virginia, and Wisconsin - "the 12 states whose results are most likely to decide the election, and where much of the campaign activity is likely to be focused," it said.
According to Gallup, Obama leads Romney by a thin margin - 47-45 percent - in those swing states, though that figure is within the poll's margin of error.
"The swing states will surely be the focus of much of the Obama and Romney campaigns' efforts this year. That is already evident from the standpoint that swing-state voters are much more likely to say they have seen a presidential campaign ad than those in non-swing states," Gallup said.
