FILE - In this Oct. 17, 2012 file photo, President Barack Obama speaks at Ohio University, in Athens, Ohio. Independent groups working to elect Republican Mitt Romney have helped him match or even exceed President Barack Obama’s TV ad spending in dozens of media markets in battleground states. But the spending disparity doesn’t tell the whole story, as Obama is still getting more value for his money with his ads. (AP Photo/Carolyn Kaster, File)
