ABBOTTSFORD, Wis. - If lady luck works his way, Rick Santorum could be using some big bucks from the Mega Millions lottery to finance his campaign.

As he picked up his ice cream order - toasted almond fudge and Heath bar ice cream - at the counter at the Hawkeye Dairy Store, Santorum told reporters he'd consider buying a lottery ticket tonight for the $640 million prize Americans across the country are hoping to win.

"[It] may be a financing mechanism for my campaign," Santorum told reporters at the Hawkeye Dairy Store, where they asked if he'd be purchasing a ticket Friday night.

Turning to an aide, he said, "Sure! Why not? Is that, have we done that yet?"

While he expressed interest in buying a ticket, it is unknown whether Santorum found the time to do so between his five campaign stops Friday.

Earlier in the day at a stop in Fond du Lac, Wis., Mitt Romney said he would not partake in the lottery but made a jab at Sheldon Adelson, the casino mogul who's poured millions into a super PAC backing Newt Gingrich, saying he's bought a few tickets himself.

"I don't have any lottery guys helping me out already," Santorum said when he heard about Romney's joke.

As they roamed through the store, an aide to Santorum told reporters the chances of becoming president are better than winning the lottery, an idea Santorum agreed with.

"By far," Santorum said. "So maybe the combination of the two will work."

Before a fish fry and bowling outing in Weston, Wis., Friday evening, Santorum and his family made a pit stop at the Hawkeye Dairy Store where he also sampled colby, cheddar and buffalo wing cheese and greeted customers at the store. As he chewed on some of the store's cheese, a woman asked that he pose for a picture with her group and she said they were able to "catch him with his mouth full of Wisconsin cheese."

Several of the voters in the store were clad in Green Bay Packers gear, and they asked the former Pennsylvania senator if he'd put on a cheese head typically worn by fans at football games.

"Ah, c'mon," Santorum said, shaking his head. "I'm a Steeler fan. There's only certain things I'll do. I went to Lambeau Field, threw passes on Lambeau field."

But as he laughed at the Packers fan's request, Santorum joked he might wear one, only "if I can cover it with a terrible towel."
