Bush won by a narrow margin of 35 electoral votes and took 50.7% of the popular vote. He swept the South and the Mountain States and took the crucial swing states of Ohio, Iowa, and New Mexico, the latter two being flipped Republican. Although Kerry flipped New Hampshire, Bush's electoral map expanded numerically. Some aspects of the election process were subject to controversy, but not to the degree seen in the 2000 presidential election. Bush won Florida by a solid five-point margin, unlike his razor-thin 2000 victory margin in the state that led to a legal challenge in "Bush v. Gore".
