Romney ad follows up Clinton speech with a flashback

(CNN) -- Bill Clinton's speech Wednesday at the Democratic National Convention was met with cheers from delegates and generally positive reviews from pundits, but Mitt Romney's campaign is using the prime-time address to remind voters of the former president's views on then-candidate Barack Obama in 2008.

"As the economy gets worse, Barack Obama calls on Bill Clinton to help his failing campaign," a narrator in the spot says before a clip is shown from an Obama campaign ad featuring Clinton.

"He's a good soldier-helping his party's president," the narrator continues. "But what did Bill Clinton say about Barack Obama in 2008?"

A clip rolls of Clinton saying "Give me a break. This whole thing is the biggest fairy tale I've ever seen."

The former president spoke those words at a campaign stop in New Hampshire during the 2008 Democratic presidential primaries. He was arguing that Obama got an easier time from the media than his wife, Hillary Clinton, who was Obama's top rival for the 2008 Democratic nomination.

Thursday's ad isn't the first time a Clinton has appeared in a Mitt Romney television advertisement. The Republican presidential nominee has released two spots featuring Hillary Clinton from her 2008 Democratic primary battle with the then-Illinois senator. The first ad, released at the end of June, uses video of Clinton campaigning against candidate Obama in Cincinnati ahead of the 2008 Ohio primary.

Clinton accused Obama of "blatantly false" attacks against her in campaign mailers, which Romney used to highlight one of Obama's 2012 ads, which was called "misleading, unfair and untrue" in a Washington Post fact check.

A second Romney spot featuring Hillary Clinton responded to an attack from Obama's campaign on Bain Capital, the private equity firm Romney co-founded and ran in the 1990s.

The ad recycled a quote from Hillary Clinton in 2008, when Clinton fired off on Obama over her opponent's latest round of blows.

"Shame on you, Barack Obama," Clinton says in the clip.
