Some of the biggest Republican donors to George W Bush's presidential campaigns are backing Rudy Giuliani, the former New York mayor, for the White House as the candidate who can beat Hillary Clinton in 2008.
Over a private lunch of sea bass and hamburgers at New York's 21 Club recently, Mr Giuliani addressed nearly three dozen of the men who helped propel Mr Bush to the presidency. They included "Pioneers", who donated more than $100,000 to Bush campaigns, and "Rangers" who gave at least $200,000.
