The Northern Mariana Islands did not participate in the November 8, 2016 general election for President of the United States, because it is a territory and not a state. However, the five non-incorporated territories that send delegates to the House of Representatives participated in the presidential primaries of both major parties.
In the presidential primaries, voters expressed their preferences for the Democratic and Republican parties' respective nominees for president. Registered members of each party only voted in their party's primary, while voters who were unaffiliated chose any one primary in which to vote. The caucuses were held in March 2016.
