Rick Santorum Reveals Why He Thinks Mitt Romney Lost in 2012

Says the Romney campaign didn't handle Obama's "you didn't build that" gaffe well

Rick Santorum ripped Mitt Romney's campaign Thursday for mishandling President Barack Obama's "you didn't build that" gaffe last summer.

The former Pennsylvania senator recalled all the business owners who spoke at the Republican National Convention.

"One after another, they talked about the business they had built. But not a single—not a single —factory worker went out there," Santorum told a few hundred conservative activists at an "after-hours session" of the Faith and Freedom Coalition conference in Washington. "Not a single janitor, waitress or person who worked in that company! We didn't care about them. You know what? They built that company too! And we should have had them on that stage."
