Clinton/Clark -- Fruit Salad for Everyone

Gen. Wesley Clark appeared with Hillary Clinton today in Des Moines at an unscheduled stop at the Drake Diner -- part of the campaign's effort to find an edge in the caucus contest, which is proving the most competitive state race en route to the Democratic nomination.

Clinton introduced diners to the general, who is because of his extensive foreign policy experience an oft-mentioned veep possibility. She also chatted with a handful of voters who worked at an area children's hospital and with a man who asked about housing issues.

"I'd love to have your support," the senator said at one point; one of the diners said she would have his.

Clinton then settled in at the counter to chat, before the cameras, with Clark and former Iowa First Lady Christie Vilsack about the challenges of campaigning over the holidays.

Clinton wondered aloud how they would keep momentum going over the holidays, saying politics that time of year isn't at the top of voters' agendas.

"You can't call them on Christmas," Vilsack said.

"You can call them on the 26th," Clark responded with a chuckle.

They also spoke about China and ways to fight global warming.

Clark called eggs his "comfort food," and both he and Clinton ordered fruit bowls, reports NBC/NJ's Athena Jones.
