This was one of the seven Democratic-held Senate seats up for election in a state that Mitt Romney won in the 2012 presidential election. Incumbent Democratic Senator Tim Johnson decided to retire instead of running for re-election to a fourth term in office. As a result, this was the first open seat election since 1978. Former South Dakota Governor Mike Rounds won the open seat, giving South Dakota an all-GOP congressional delegation for the first time since 1963 and giving Republicans control of both of South Dakota's Senate seats for the first time since 1987. Businessman Rick Weiland ran unopposed for the Democratic nomination. Also running were two independent candidates: former Republican U.S. Senator Larry Pressler, who held this seat from 1979 to 1997, and former Republican state senator Gordon Howie. Democratic primary Candidates Declared Rick Weiland, businessman, former staffer for Tom Daschle, nominee for South Dakota's at-large congressional district (SD-AL) in 1996 and candidate for SD-AL in 2002http://www.argusleader.com/article/20130508/NEWS/130508043/Argus-exclusive-Democrat-Rick-Weiland-announces-U-S-Senate-run?nclick_check=1 https://archive.today/20130628111416/http://www.argusleader.com/article/20130508/NEWS/130508043/Argus-exclusive-Democrat-Rick-Weiland-announces-U-S-Senate-run?nclick_check=1 dead June 28, 2013 Update: Rick Weiland's Senate run draws support from Daschle, others May 8, 2013 May 9, 2013 Argus Leader http://www.ctpost.com/news/article/Field-for-South-Dakota-US-Senate-seat-set-5350345.php https://web.archive.org/web/20140407085348/http://www.ctpost.com/news/article/Field-for-South-Dakota-US-Senate-seat-set-5350345.php dead April 7, 2014 Field for South Dakota US Senate seat set March 26, 2014 March 26, 2014 CTPost Withdrew Kevin Artz, businessmanhttp://www.aberdeennews.com/news/local/article_0c5aa366-7834-5dc7-bf23-88c1f7a7fa0b.html Resident set to run for Democratic nomination for Senate February 14, 2014 March 21, 2014 Aberdeen News Wynn Kimberlyhttp://wnax.com/news/180081-2nd-democrat-joins-senate-race/ 2nd Democrat Joins Senate Race February 14, 2014 March 21, 2014 WNAX (AM) Henry Jo Sinkie, rancher and resort ownerhttp://madvilletimes.com/2014/02/democrat-henry-sinkie-seeking-democratic-nomination-for-u-s-senate/ https://web.archive.org/web/20140813015852/http://madvilletimes.com/2014/02/democrat-henry-sinkie-seeking-democratic-nomination-for-u-s-senate/ usurped August 13, 2014 Democrat Henry Sinkie Seeking Democratic Nomination for U.S. Senate February 3, 2014 March 21, 2014 Madville Times Heidelberger Cory Declined Jason Frerichs, minority leader of the South Dakota Senate (running for re-election)http://politicalsmokeout.tumblr.com/post/51646261255/frerichs-political-future Frerichs' political future May 29, 2013 July 9, 2013 Political Smokeouthttp://sdsos.gov/content/html/elections/electvoterpdfs/2014/ElectionCandidates.pdf Current Candidates for Primary Election March 21, 2014 dead https://web.archive.org/web/20140325222718/http://sdsos.gov/content/html/elections/electvoterpdfs/2014/ElectionCandidates.pdf March 25, 2014 Stephanie Herseth Sandlin, former U.S. representativehttp://atr.rollcall.com/stephanie-herseth-sandlin-not-running-for-senate/ Stephanie Herseth Sandlin Not Running for Senate May 13, 2013 May 13, 2013 Roll Call Kyle Trygstad June 9, 2013 https://web.archive.org/web/20130609223217/http://atr.rollcall.com/stephanie-herseth-sandlin-not-running-for-senate/ dead Brendan Johnson, United States attorney for the District of South Dakota and son of incumbent Senator Tim JohnsonStephanie Herseth Sandlin won't run in South Dakota - James Hohmann - POLITICO.com Tim Johnson, incumbent U.S. senatorhttps://www.usatoday.com/story/news/politics/2013/03/25/tim-johnson-senate-retire-south-dakota/2018537/ Report: Democratic Sen.
