The Romney campaign ad, "Give Me A Break": 

What it says: "As the economy gets worse, Barack Obama calls on Bill Clinton to help his failing campaign. ... But what did Bill Clinton say about Barack Obama in 2008?"

The ad includes a clip of Clinton saying in January of 2008: "Give me a break. This whole thing is the biggest fairy tale I've ever seen." Clinton was campaigning for Hillary Clinton in 2008 at the time, when he made the remark regarding Obama's claim that he consistently opposed the Iraq War. 

What it means: You know that guy everyone is pointing to as Obama's most valuable surrogate? He wasn't as big a fan in 2008.

Who will see it: The Romney campaign did not immediately provide information about where the ad will air.
