A day after President Obama officially accepted the Democratic nomination for reelection with a prime-time address in Charlotte, Mitt Romney released 15 television ads in eight swing states, each of which argues that Americans are not better off today then they were when Obama took office. 

Each of the ads begins with a clip from Romney's convention speech, which he delivered in Tampa last week.

"This president can ask us to be patient," Romney said. "This president can tell us it was someone else's fault. But this president cannot tell us that you are better off today than when he took office."

The ads are running in Colorado, Florida, Iowa, Nevada, New Hampshire, North Carolina, Ohio and Virginia.

In every spot, the first third is the same. The last 20 seconds, however, vary from ad to ad, as each is tailored to address a specific issue, including defense spending, manufacturing, energy and government regulation.

"Here in Virginia, we are not better off under President Obama," says one of the spots. "His defense cuts threaten over 130,000 jobs, lowering home values, putting families at risk. The Romney plan? Tax cuts for middle class families."

"Here in Florida, we are not better off under President Obama. Home values collapsed; home construction jobs lost; high rate of foreclosure," says another spot. "Romney's plan? Provide alternatives to foreclosure. End the mortgage lending freeze. Create over 700,000 new jobs for Florida."

In all states except New Hampshire and Nevada, more than one version of the ad is running.
