"McCain won a 48%-30% victory over Bush in the New Hampshire primary. In the South Carolina primary, however, Bush soundly defeated McCain. Some credit Bush's win to the fact that it was the first major closed primary in
2000, which negated McCain's strong advantage among independents. Some McCain supporters blamed it on the Bush campaign, accusing them of mudslinging and dirty tricks, such as push polling that implied that McCain's adopted Bangladeshi-born daughter was an African-American child he fathered out of wedlock.[6] McCain's loss in South Carolina damaged his campaign. Although McCain won a few additional primaries, Bush took the majority of the remaining contests and the nomination at the Republican National Convention in Philadelphia."
