2016 Democratic Party presidential primaries

The 2016 Democratic Party presidential primaries and caucuses took place in the United States. It takes place before to the 2016 general election to elect the Democratic Party's nominee for the Presidency of the United States. They were held between February 1 and June 14. President and 2012 nominee, Barack Obama could not stand for re-election due to term limits under the Twenty-second Amendment.
Candidates.
Hillary Clinton, then Secretary of State, decided to run for president in April 2015. Clinton had served as a U.S. Senator (2001–09) and was the First Lady of the U.S. (1993–2001). A January 2013 "Washington Post"–ABC News poll showed that she had high popularity among the American public. This polling data made many political critics and observers to anticipate that Clinton would launch a second presidential bid in 2016, entering the race as the early front-runner for the Democratic nomination.
On May 26, 2015, Independent U.S. Senator Bernie Sanders officially announced his run as a presidential candidate for the Democratic nomination, after an informal announcement in April that year, and speculation since early 2014. Sanders had served as Mayor of Burlington, Vermont (1981–1989), as Vermont's sole U.S. Representative (1991–2007), and as Vermont's junior Senator (2007–present). Bernie Sanders is currently seen as the biggest rival to Hillary Clinton, backed up by a strong grassroots campaign and social media following. His campaign picked up attention and mass support. However, in recent poll numbers, Clinton is leading Saunders nationally by 12.7 percent.
In May 2015, Maryland governor Martin O'Malley announced his campaign. He withdrew after the Iowa primaries. Rhode Island governor Lincoln Chafee announced his campaign in June 2015. After poor polling numbers, he dropped out before the primaries in October 2015. Former Virginia senator Jim Webb announced his campaign in the summer of 2015. He dropped out in October 2015 after a poor debate performance. Professor Lawrence Lessig announced his campaign in September 2015. He dropped out a month later after poor polling numbers.
