The 2017 United States Senate special election in Alabama took place on December 12, 2017, in order to fill the Class II Senate seat for the remainder of the six-year term. A vacancy arose after incumbent Republican Senator Jeff Sessions resigned from the Senate on February 8, 2017 to serve as the 84th U.S. attorney general. On February 9, 2017, then-Governor Robert J. Bentley appointed Luther Strange, the attorney general of Alabama, to fill the vacancy until a special election could take place. The special election was scheduled for December 12, 2017.

Doug Jones, a former U.S. attorney for the Northern District of Alabama, won the Democratic primary election. Roy Moore, a former chief justice of the Supreme Court of Alabama, competed with Strange and U.S. Representative Mo Brooks in the August 15, 2017, Republican primary; the two highest vote-getters, Moore and Strange, advanced to a runoff. President Donald Trump supported Strange during the primary runoff, as did much of the Republican establishment in the Senate.Ball, Molly. "The Alabama Senate Race Gets Moore Strange", The Atlantic (August 16, 2017)."Sexual misconduct accusations transform Alabama Senate race", Associated Press via ABC News (November 10, 2017): "Virtually the entire Republican establishment — including President Donald Trump — opposed Moore's primary bid in September." Moore won the primary runoff on September 26, 2017.Strauss, Daniel. "Moore crushes Strange in Alabama Senate primary", Politico (September 26, 2017).

Following the primaries, Moore was expected to easily win the general election. Polling showed him with a clear lead, and Alabama is known for its overwhelming support for Republicans. However, the race was upended in mid-November 2017, when multiple women alleged that Moore had made unwanted advances or sexually assaulted them when he was in his early thirties and they were aged between 14 and 22, attracting widespread national media coverage of the election. As a result of these allegations, many national Republican leaders and office holders called for Moore to withdraw from the special election, rescinded their endorsements of him, and stopped funding his campaign. Trump and many Alabama Republicans reaffirmed their support. At the time of the revelations, it was too late to remove his name from the ballot.

On December 12, 2017, Jones won by a margin of 1.63% or 21,924 votes, in a victory that was widely labeled an upset. Moore refused to concede defeat. Jones was sworn into office on January 3, 2018, becoming the first Democratic U.S. senator from Alabama since Howell Heflin left office in 1997. This was the first and only time Democrats had won a statewide election in Alabama since 2008, when Lucy Baxley was elected president of the Alabama Public Service Commission.

Background

Potential appointees Following then-President-elect Donald Trump's nomination of then-Senator Sessions to be U.S. attorney general, Robert Aderholt, a member of the United States House of Representatives, had asked to be appointed to the seat. Representative Mo Brooks had also expressed interest in the seat, while Strange had stated before being selected that he would run for the seat in the special election whether or not he was appointed. Other candidates Governor Bentley interviewed for the Senate appointment included Moore; Del Marsh, the president pro tempore of the Alabama Senate; and Jim Byard, the director of the Alabama Department of Economic and Community Affairs.

A vacancy arose from Senator Jeff Sessions' February 8, 2017 resignation to serve as the 84th U.S. attorney general. On February 9, 2017, Governor Robert J. Bentley appointed State Attorney General Luther Strange to fill the vacancy until a special election could take place. Bentley controversially scheduled the special election to occur in 2018 instead of sooner."Election to Fill the Vacancy of Sen. Jeff Sessions", Legislative Reference Service (February 13, 2017). When Kay Ivey succeeded Bentley as Alabama's governor, she rescheduled the special election for December 12, 2017, a move she said was made to adhere with state law.

Republican primary Campaign The Republican primary attracted national attention, especially following Trump's endorsement of incumbent Senator Luther Strange. Strange was backed by several key figures within the Republican establishment, most notably Mitch McConnell, the Senate Majority Leader. His two main rivals in the primary were former state judge Roy Moore and Congressman Mo Brooks. While Strange was expected to advance through the first round of the primary, almost every opinion poll showed him trailing Roy Moore in a potential runoff. Strange placed second behind Roy Moore, securing a spot in the runoff.

Results

Runoff President Donald Trump supported Strange during the primary runoff, in addition to much of the Republican establishment in the Senate, including Senate Majority Leader Mitch McConnell, who made the success of Strange's candidacy a major priority. Trump's efforts on behalf of Strange included tweeting and a rally in Huntsville, Alabama. Vice President Mike Pence campaigned for Strange as well.Rogin, Ali. "Roy Moore defeats Trump-backed Sen. Luther Strange in Alabama GOP primary runoff", ABC News (September 26, 2017).Scherer, Michael. "Moore wins Republican Senate primary, dealing blow to GOP establishment" (September 27, 2017): "He also won despite a last-minute push by Trump for Strange that included a barrage of late tweets and a rally Friday in Alabama." With McConnell's help, Strange outspent Moore by a margin of 10-to-1."Roy Moore beats Trump-backed 'Big Luther' in Alabama Republican Senate primary", The Guardian (September 17, 2009).

National interest in the race dramatically increased in the month before the runoff. Strange maintained his endorsement from Trump, who campaigned for him in Huntsville during the closing days of the campaign. Trump's endorsement of Strange sparked criticism among his own base, many of whom preferred Moore and detested Strange for being seemingly too friendly with the GOP establishment. Several notable figures close to Trump broke from the president to endorse Moore, including HUD Secretary Ben Carson and Breitbart Executive Chairman Steve Bannon. Despite Trump's endorsement, Strange was defeated by Roy Moore in the runoff, 54.6%-45.4%.

Moore won the primary runoff on September 26, 2017. This was the first time that an incumbent U.S. senator having active White House support lost a primary since Arlen Specter lost to Joe Sestak in 2010.Martin, Jonathan and Burns, Alexander. "Roy Moore Wins Senate G.O.P. Runoff in Alabama", The New York Times (September 26, 2017): "Mr. Strange's defeat was the first time an incumbent senator with active White House support has lost since 2010, when Arlen Specter, the longtime senator of Pennsylvania, was beaten in a Democratic primary after switching parties."
