Final answer:
In the 2004 election, George W. Bush narrowly won reelection, making 'George W. Bush narrowly won reelection' the correct statement regarding the election outcome.
Step-by-step explanation:
The statement that best describes the outcome of the 2004 election is A. George W. Bush narrowly won reelection. After a controversial and closely contested election in 2000, where George W. Bush won the presidency by a slim margin in the Electoral College against Democratic opponent Al Gore, Bush sought a second term in 2004. Campaigning on a platform that promised continuity in the face of the ongoing War on Terror initiated after the attacks of September 11, 2001, Bush was able to secure a narrow victory once again. During the 2004 elections, Bush's win solidified the Republicans' hold on both legislative and executive branches of government, with increased majorities in both the Senate and the House.
