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."
