Romney primarily is running a spot in which he promises to boost the economy through manufacturing, energy and cracking down on China.
"Let me tell you how I will create 12 million jobs when President Obama couldn't," Romney says.
Both sides are being buffeted by independent groups.
Romney is getting a big assist from two super political action committees, Restore Our Future and American Crossroads. The pro-Obama Priorities USA Action is running an ad saying Romney would cut early childhood education if elected.
Among those who aren't watching is Paul Gentille, a 67-year-old Obama supporter from St. Petersburg.
He said he tuned out the ads months ago. "Everyone I know has already made up their mind. The ads are kind of annoying," he said. "It's a shame to see so much money being spent."
On the other side is Julie Harris, also of St. Petersburg.
The 33-year-old stay-at-home mom said she always planned to support Romney and that his ads made her "more enthusiastic" about doing so. One particular Obama ad stuck out to her: the ad assailing Romney's pledge to end federal support of public television and the Sesame Street character Big Bird. Even though she's a fan of public TV, she says that ad won't affect her vote.
