another story we're going to be following throughout the afternoon. jenna: j.d., thank you. >> reporter: you bet. gregg: shaking hands and kissing babies, an age-old political tradition, to be sure, but candidates can really have a hard time gaining traction when their ground game is overshadowed these days by the very expensive television ads and online campaigns. joel sawyer joins us, former executive director of south carolina's republican party, a member of the huntsman campaign. i was reading a story that says rick santorum is winning the ground game, he's been seeing everybody, and he's been in all 46 counties. but you look at his poll numbers, and he's not, he may be winning the ground game, but that's not winning, is it? >> no, it's not. i mean, but, you know, you've got to give rick santorum a lot of credit. it's been hard to go to a county republican meeting in south carolina without tripping over the guy. he's invested a lot of time in the grassroots.
