The 2016 United States Senate elections were held on November 8, 2016. The presidential election, House elections, 14 gubernatorial elections, and many state and local elections were held concurrently.
In the elections, 34 of the 100 seats—all Class 3 Senate seats—were contested in regular elections; the winners served 6-year terms until January 3, 2023. Class 3 was last up for election in 2010, when Republicans won a net gain of 6 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. Although Democrats made a net gain of 2 seats and did not lose any of their seats, Republicans retained control of the Senate for the 115th United States Congress. The 2 Democratic gains came from the defeats of incumbents Kelly Ayotte in New Hampshire and Mark Kirk in Illinois by Maggie Hassan and Tammy Duckworth, respectively.
Despite Republicans retaining control of the Senate, 2016 marked the first time since 1986 where Democrats made a net gain of seats in Class 3. This is also the only election cycle since the popular-vote election of senators was mandated by the Seventeenth Amendment in 1913 that the winning party in every Senate election mirrored the winning party for their state in the presidential election.[2][3] This feat had nearly been accomplished earlier in 1920, which also involved the Class 3 Senate seats, and nearly repeated in 2020; in both cases, every state, with the exception of Kentucky in 1920 and Maine in 2020, voted for the same party in the presidential election and their Senate election. In addition, this election marked the first time since 2000 in which the party in opposition to the elected or reelected presidential candidate made net gains in the Senate; both cases involved the election of a Republican president and the Democrats making gains in the Senate.
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.
As of 2024, this is last time Republicans won Senate races in Arizona, Georgia, or Pennsylvania. It is also the last election cycle at least until 2026 where there were no special elections.
Results summary[edit]

Final pre-election predictions[edit]
Several sites and individuals publish predictions of competitive seats. These predictions look at factors such as the strength of the incumbent (if the incumbent is running for reelection) and the other candidates, and the state's partisan lean (reflected in part by the state's Cook Partisan Voting Index rating). The predictions assign ratings to each seat, indicating the predicted advantage that a party has in winning that seat.
Most election predictors used:
- "tossup": no advantage
- "tilt" (used by some predictors): advantage that is not quite as strong as "lean"
- "lean": slight advantage
- "likely" or "favored": significant, but surmountable, advantage
- "safe" or "solid": near-certain chance of victory
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's Upshot gave the Democrats a 60% chance of winning the Senate on August 24, 2016;[4] on September 23, their model gave Republicans a 58% chance to maintain control.[5]

Primary dates[edit]
This table shows the primary dates for regularly-scheduled elections. It also shows the type of primary.
- "Open" primary: any registered voter can vote in any party's primary
- "Closed" primary, only voters registered with a specific party can vote in that party's primary.
- "Top-two" primary, all candidates run against each other regardless of party affiliation, and the top two candidates advance to the second round of voting. (In Louisiana, a candidate can win the election by winning a majority of the vote in the first round.)
- All of the various other primary types are classified as "hybrid." Alaska in 2008 provides one example of a hybrid primary: The Democratic Party allowed unaffiliated voters to vote in its primary, while the Republican Party only allowed party members to vote in its primary.[13]

Incumbent Republican Richard Shelby won re-election to a sixth term in office. The primaries were held on March 1. Ron Crumpton, a marijuana legalization activist, was the Democratic nominee.[16] 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[by whom?] that Shelby could also face a Tea Party primary challenger, due to his lengthy tenure and support for federal largesse. However, that did not happen, in part due to his large campaign war chest, which stood at $19.4 million as of September 2015.[16] 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.[75][76][77] Shelby announced in January 2015 that he would run for re-election.[78]

Four-term senator Barbara Boxer (Democrat) was re-elected with 52% of the vote in 2010. Boxer declined to run for re-election.[117] California Attorney General Kamala Harris and U.S. Representative Loretta Sanchez, both Democrats, finished first and second, respectively,[118] in California's nonpartisan blanket primary, and contested the general election. As such, Boxer's successor was guaranteed to be a Democrat.[119] This marked a historic first such occasion in California, ever since the Senate elections began in 1914.
Other Democrats on the primary ballot included "President" Cristina Grappo, Massie Munroe, Herbert Peters, Emory Rogers, and Steve Stokes.[120] Among the potential candidates who declined to run were Governor Jerry Brown, Lieutenant Governor Gavin Newsom, U.S. Representatives Xavier Becerra and Adam Schiff, and Los Angeles Mayor Eric Garcetti.
Former state Republican Party chairs Tom Del Beccaro[121] and Duf Sundheim,[122] and former state senator Phil Wyman[123][124] ran, along with Don Krampe,[125] Tom Palzer,[126] Karen Roseberry,[127] Greg Conlon, Von Huogo, Jerry Laws, Ron Unz, Jarrell Williamson, and George Yang.[120] State Assemblymen Rocky Chavez was running as well,[128] but withdrew from the race.[129] Republicans who were once considered potential candidates but ruled out runs included San Diego Mayor Kevin Faulconer, former Assistant Secretary of the Treasury for Financial Stability and 2014 gubernatorial nominee Neel Kashkari, U.S. Representative Darrell Issa, and businesswoman and nominee for the U.S. Senate in 2010 Carly Fiorina.[130]
Independent Mike Beitiks ran on a single-issue climate change platform.[131]
Polling conducted by the SurveyUSA from March 30, 2016 to April 3, 2016 indicated that Harris was ahead with 26%, compared to Rep. Sánchez with 22%, Del Beccaro with 8%, Wyman with 8%, and Sundheim with 3%; 7% of those polled were supporting other candidates, and 24% were undecided.[132]
Harris won the election with 62% of the vote to Sanchez's 38%.

One-term senator Marco Rubio (Republican) was elected in a three-way race with 49% of the vote in 2010. In April 2014, Rubio stated that he would not run for both the Senate and President in 2016, as Florida law prohibits a candidate from appearing twice on a ballot.[156] In April 2015, he announced that he would run for President and would not seek re-election.[157] After suspending his campaign on March 15, 2016, Rubio announced on June 22, 2016 that he had changed his mind and would run for re-election.[30]
