context_page_description: The 2016 Democratic Party presidential primaries and caucuses were a series of electoral contests organized by the Democratic Party to select the 4,051 delegates to the 2016 Democratic National Convention held July 25–28 and determine the nominee for President of the United States in the 58th U.S. presidential election. The elections took place within all fifty U.S. states, the District of Columbia, five U.S. territories, and Democrats Abroad and occurred between February 1 and June 14, 2016.
  A total of six major candidates entered the race starting April 12, 2015, when former Secretary of State and New York Senator Hillary Clinton formally announced her second bid for the presidency. She was followed by Vermont Senator Bernie Sanders, former Governor of Maryland Martin O'Malley, former Governor of Rhode Island Lincoln Chafee, former Virginia Senator Jim Webb and Harvard Law Professor Lawrence Lessig. A draft movement was started to encourage Massachusetts Senator Elizabeth Warren to seek the presidency, but Warren declined to run, as did incumbent Vice President Joe Biden. Webb, Chafee, and Lessig withdrew prior to the February 1, 2016, Iowa caucuses.
context_section_description: On April 19, Clinton won New York by 16 points. While Sanders performed well in Upstate New York and with younger voters, Clinton performed well among all other age groups and non-whites, and she won a majority in all boroughs of New York City.
  Five Northeastern states held primaries a week later on April 26. The day was dubbed the "Super Tuesday III" or the "Acela Primary" after Amtrak's Acela Express train service that connects these states. Clinton won in Delaware, Maryland, Pennsylvania and Connecticut while Sanders won the Rhode Island primary.
  On May 3, Sanders pulled off a surprise victory in the Indiana primary, winning over Clinton by a five-point margin despite trailing in all the state's polls. Clinton then won the Guam caucus on May 7 and, on May 10, she won the non-binding Nebraska primary while Sanders won in West Virginia.
  Clinton narrowly won Kentucky on May 17 by half a percentage point and gained one delegate, after heavily campaigning in the state. On the same day, Sanders won his second closed primary in Oregon where he gained nine delegates, a net gain of eight on the day. Clinton then went on to win the non-binding Washington primary on May 24.
