Voters elected members of the U.S. House of Representatives and U.S. Senate, as well as a new President of the United States, Republican Donald Trump. The 2016 Election Day was the second Tuesday in November, the date of all federal elections. In the 2016 presidential election, voters chose 34 of the 100 members of the U.S. Senate and all 435 members of U.S. House of Representatives. The political makeup of Congress changed only slightly, but voters awarded both the House and Senate, as well as the White House, to the Republicans. Congress requires elections to be held on Tuesdays. In fact, elections for President, U.S House of Representatives, and Senate have been held on Tuesdays since 1845. Despite the requirements on when Election Day is to be held, voters in about two-thirds of states were allowed to cast their ballots beforehand under "early voting" laws. A large number of voters cast their ballots before Election Day because interest was high in the presidential race.
