US:Republican presidential candidate Rudy Giuliani has asked senior campaign staff to work without pay this month as he channels all his resources into winning Florida's primary on January 29th.
Mr Giuliani came fourth in Iowa and New Hampshire and is considered unlikely to fare better in next week's primaries in Michigan and Nevada.
He hopes, however, that a big victory in Florida will propel him into contention for the nomination on February 5th, when more that 20 states, including New York and California, go to the polls.
"We have enough money, but we could always use more money. We want to make sure we have enough to win," campaign manager Mike DuHaime, one of about a dozen staff who are forgoing their salary this month, told the Associated Press.
Mr Giuliani's campaign says it had $7 million cash on hand on December 31st to spend on the primary campaign but he may have spent much of that already this year on advertising in New Hampshire and Florida.
Mr Giuliani made little impact during a Republican candidates' debate in South Carolina on Thursday evening which saw frontrunner John McCain avoid any stumbles and former Tennessee senator Fred Thompson show animation for the first time with a spirited attack on the conservative credentials of former Arkansas governor Mike Huckabee.
"This is a battle for the heart and soul of the Republican Party and its future. On the one hand you have the Reagan revolution . . . on the other hand you have the direction that Governor Huckabee would take us . . . liberal economic policies, liberal foreign policies," Mr Thompson said.
Mr Huckabee later drew loud applause when he defended his support in 1998 for a statement that a wife should "submit graciously to the servant will of her husband". An ordained Baptist minister who has campaigned as a "Christian leader", Mr Huckabee said he was "not the least bit ashamed of my faith" but that he did not impose it on others as governor and would not as president.
He said the citation was from the New Testament letter of St Paul to the Ephesians, and "the point is that as wives submit themselves to their husbands, the husbands also submit themselves" to their wives.
"That's why marriage is an important institution, because it teaches us how to love," he said.
Mr Thompson and Mr Huckabee are battling for the conservative vote in South Carolina, where Mr McCain is also hoping for victory next Saturday.
Mr Huckabee, Mr McCain and former Massachusetts governor Mitt Romney are in a three-way race in Michigan next Tuesday, with Mr Romney banking on victory there to keep his candidacy viable. The Democrats are not contesting primaries in Michigan and Florida which were scheduled in January against the wishes of the party authorities.
