The series of presidential primary elections and caucuses took place between February 1 and June 14, 2016, staggered among the 50 states, the District of Columbia and U.S. territories. This nominating process is also an indirect election, where voters cast ballots for a slate of delegates to a political party's nominating convention, who then in turn elect their party's presidential nominee. The 2016 Republican National Convention will take place from July 18-21, 2016 in Cleveland, Ohio, while the 2016 Democratic National Convention will take place from July 25-28, 2016 in Philadelphia, Pennsylvania.
