South Carolina ? About a dozen senior campaign staffers for Rudy Giuliani are forgoing their January paychecks, a sign of possible money trouble for the Republican presidential candidate and last year’s national front-runner.

“We didn’t ask anybody to do it,” Giuliani told reporters Friday after a town hall meeting at a charter school in Coral Springs, Fla.

At the end of December, the campaign had $12.7 million cash on hand, $7 million of which could be used for the primary, said Mike DuHaime, Giuliani’s campaign manager and one of those who now is working for free. He disputed the notion of a cash-strapped operation and said Giuliani continues to bring in money; several fundraisers are scheduled this week in Florida.
