context_page_description: The 2018 United States Senate elections were held on November 6, 2018. 33 of the 100 seats were contested in regular elections while two others were contested in special elections due to Senate vacancies in Minnesota and Mississippi. The winners were elected to six-year terms running from January 3, 2019, to January 3, 2025. Senate Democrats had 26 seats up for election while Senate Republicans had nine seats up for election.
  To maintain their working majority of 50 Senators and Republican Vice President Mike Pence, Republicans could only afford a net loss of one Senate seat in the 2018 elections. The Republicans had a 52-48 majority after the 2016 elections, but they lost a seat in Alabama in December 2017 after senator Jeff Sessions resigned to become the U.S. Attorney General and Democrat Doug Jones won the resulting special election. Three Republican-held seats were open as a result of retirements in Tennessee, Utah and Arizona, while every Democratic incumbent ran for re-election.
context_section_description: One-term Democrat Martin Heinrich was elected with 51% of the vote in 2012. He ran. Mick Rich won the Republican nomination unopposed.
  Aubrey Dunn Jr., New Mexico Commissioner of Public Lands and otherwise the first Libertarian to ever hold statewide elected office in history, announced his run for the seat, but stepped aside in August to allow former Governor of New Mexico, Gary Johnson's candidacy.
  Heinrich was easily re-elected, defeating Rich and Johnson.
