Another subltle message about Gingrich from Ann Romney

It seems like just last week I was writing about Mitt Romney's wife Ann saying she wouldn't make "any statement...on a personal level" about Newt Gingrich's past extramarital affairs, even though she kind of has been. Oh, it was last week.

There's a new ad from the Romney campaign narrated by Ann and you can't help but wonder what she's talking about when she says "[I]f you really want to know how a person will operate, look at how they've lived their life." Especially when she says that over old photos of her and Mitt.

Who could she possibly be speaking of?

Watch the ad, titled "Character":
