New York, UNITED STATES: (FILES) Former US President Bill Clinton (L) speaks to Arkansas Governor Mike Huckabee (R) in this 03 May, 2005 file photo at Public School 128 in New York. Former Arkansas governor Mike Huckabee joined 28 January 2007 the crowded field of Republicans in the race for the White House, saying America needed "positive" leadership to revive the "national soul." Huckabee, a conservative Christian, is an immediate underdog for his party's nomination in 2008, as Republican heavyweights such as Senator John McCain and former New York mayor Rudolph Giuliani are eyeing the presidency.
