Mitt Romney Ad Hits Obama "Horses and Bayonets" Line

Ad says the president doesn't take national security seriously

Mitt Romney is sticking to his attack on the president for the size of the Navy. He released a radio ad in New Hampshire, Florida and Virginia on Thursday using their exchange from this week's debate to say President Barack Obama does not take military concerns seriously.

"To Mitt Romney, that's a problem," a voiceover says in the ad. "To President Obama, it's a chance to deliver a punch line."
