Mitt Romney, "Apology Tour" 

What it says: The ad uses a long clip from Monday's foreign policy debate, in which Mitt Romney accused President Obama of launching "an apology tour," of visiting various nations … and criticizing America."

What it means: Romney was more cautious and conciliatory in this debate than he has been in the past. This ad uses one of his more aggressive lines to take the fight back to Obama. The Fact Checker gave the "apology tour" claim Four Pinocchios, saying "the apology tour never happened." 

Who will see it: Romney has recently bought time in Colorado, Florida, Iowa, New Hampshire, Nevada, North Carolina, Ohio and Virginia. But this ad seems designed more for Beltway buzz than swing state undecideds.
