The presidential election, House elections, 14 gubernatorial elections, and many state and local elections were held on the same date. In the 2016 Senate elections, 34 of the 100 seats -- all class 3 Senate seats -- were contested in regular elections ; the winners will serve six - year terms until January 3, 2023. Class 3 was last up for election in 2010, when Republicans won a net gain of six seats. In 2016, Democrats defended 10 seats, while Republicans defended 24 seats. Republicans, having won a majority of seats in the Senate in 2014, held the Senate majority with 54 seats before this election. Democrats won a net gain of two seats. Republicans retained control of the Senate for the 115th United States Congress. Only two incumbents lost their seats, Kelly Ayotte of New Hampshire and Mark Kirk of Illinois, to Democrats Maggie Hassan and Tammy Duckworth, respectively. Despite Republicans retaining control of the Senate, 2016 marks the first time since 1986 that Democrats made a net gain of seats in class 3. This is the first and only election since the passage of the Seventeenth Amendment in 1913 where the winning party in every Senate election mirrored the winning party for their state in the presidential election. This election marks the first time since 2000 in which the party in opposition to the elected or reelected presidential candidate made net gains in the Senate, with both cases being a Republican president and Democratic gains in the Senate. Also in both cases, the president won in the electoral college but lost the popular vote. With the retirement of Harry Reid, Chuck Schumer became the Democratic leader after the elections, while Mitch McConnell retained his position as Senate Majority Leader.

These predictions look at factors such as the strength of the incumbent ( if the incumbent is running for re-election ), the strength of the candidates, and the partisan leanings of the state ( reflected in part by the state 's Cook Partisan Voting Index rating ). The predictions assign ratings to each seat, with the rating indicating the predicted advantage that a party has in winning that seat. Most election predictors use `` tossup '' to indicate that neither party has an advantage, `` lean '' to indicate that one party has a slight advantage, `` likely '' or `` favored '' to indicate that one party has a significant but not insurmountable advantage, and `` safe '' or `` solid '' to indicate that one party has a near - certain chance of victory. Some predictions also include a `` tilt '' rating that indicates that one party has an advantage that is not quite as strong as the `` lean '' rating would indicate. Where a site gives a percentage probability as its primary indicator of expected outcome, the chart below classifies a race as follows : Tossup : 50 - 55 % Tilt : 56 - 60 % Lean : 61 - 75 % Likely : 76 - 93 % Safe : 94 - 100 % The New York Times ' Upshot gave the Democrats a 60 % chance of winning the Senate on August 24, 2016 ; on September 23, their model gave Republicans a 58 % chance to maintain control. All seats classified with at least one rating of anything other than `` safe '' or `` solid '' are listed below. State PVI Incumbent result Cook Nov. 2 2016 Sabato Nov. 7 2016 Roth.

The primaries were held on March 1. Ron Crumpton, a marijuana legalization activist, was the Democratic nominee. Shelby won re-election with 63.9 % of the vote. Shelby was first elected to the Senate in 1986 as a Democrat and was easily re-elected in 1992 as such. He switched his party affiliation to Republican on November 9, 1994, one day after the Republicans won control of both houses in the midterm elections. He won his first full term as a Republican in 1998 by a large margin and faced no significant opposition in 2004 or 2010. Following the divisive Republican primary in Mississippi ahead of the 2014 election in which Senator Thad Cochran was almost defeated, it had been speculated that Shelby could also face a Tea Party primary challenger, due to his lengthy tenure and support for federal largesse. However, that did n't happen, in part due to his large campaign war chest, which stood at $19.4 million as of September 2015. If Shelby had decided to retire, numerous high - profile Alabama Republicans were speculated to run, including U.S. Representatives Robert Aderholt, Mo Brooks, Bradley Byrne, Gary Palmer, Martha Roby, and Mike Rogers, State Treasurer Young Boozer, State Speaker Mike Hubbard, Lieutenant Governor Kay Ivey, State Senate President Pro Tempore Del Marsh, Secretary of State John Merrill, U.S. Appeals Court Judge William H. Pryor, Jr., former Governor Bob Riley, and Attorney General Luther Strange. Shelby announced in January 2015 that he would run for re-election.

She was 59 years old in 2016. She ran for re-election. Thomas Lamb, a candidate for the State House in 2006, and Bob Lochner filed to run against Murkowski.

Dunleavy, former Lieutenant Governor Mead Treadwell, and former Mayor of Anchorage Dan Sullivan.

Potential Democratic candidates included State Senator Dennis Egan, State Representative Andy Josephson, State Senator Bill Wielechowski, State Senator Hollis French and State Senate Minority Leader Johnny Ellis. Former Senator Mark Begich was mentioned as a possible candidate, but he declined to run. Murkowski won her primary on August 16, 2016 with 72 percent of the vote. Joe Miller received the Libertarian nomination and will run against Murkowski in the general election. Anchorage attorney and veteran Margaret Stock ran as an Independent candidate.
