Hillary Clinton 2016 presidential campaign

In 2016, Hillary Clinton ran unsuccessfully for president of the United States. Clinton ran as the Democratic Party's candidate for president, in which she became the first woman to win a presidential nomination by a major U.S. political party. Prior to running, Clinton served as the United States secretary of state in the administration of Barack Obama from 2009 to 2013, a U.S. senator representing New York from 2001 to 2009, and the first lady of the United States, as the wife of Bill Clinton, from 1993 to 2001. She was defeated in the general election by the Republican candidate, businessman Donald Trump.

Clinton announced her candidacy on April 12, 2015. Her main competitor in the Democratic primaries was Vermont Senator Bernie Sanders, who ran as a more progressive candidate in the primary. Clinton became the presumptive nominee of the Democratic Party on June 6, 2016, having received the required number of delegates. On July 22, she announced Virginia Senator Tim Kaine as her running mate, and the two were formally nominated at the 2016 Democratic National Convention on July 26.

Clinton received the most support from middle aged and older voters, as well as from African-American, Latino and older female voters. She focused her platform on several issues, including expanding racial, LGBTQ, and women's rights, raising wages and ensuring equal pay for women, and improving healthcare.

Clinton lost the general election to Republican Donald Trump on November 9, 2016; she conceded the following day. Had Clinton been elected, she would have been the first female and first spouse of a president to serve as president of the United States.

Clinton's narrow, unprecedented losses in the blue wall states of Michigan, Pennsylvania, and Wisconsin were considered key to her defeat.
