The2008 United States presidential election in South Dakota took place on November 4, 2008, and was part of the2008 United States presidential election. Voters chose three representatives, or electors to theElectoral College, who voted forpresident andvice president.

South Dakota was won by Republican nomineeJohn McCain by an 8.4 point margin of victory. Prior to the election, 16 of 17 news organizations considered this a state McCain would win, or otherwise considered as ared state. Like the other states located in theGreat Plains region, South Dakota is a predominantlyrural and sparsely populated state withconservative voting tendencies which favors the Republicans, who dominate elections at the state and federal level. Although South Dakota stayed in the GOP column in 2008 as RepublicanJohn McCain carried the state with 53.16% of the popular vote, Obama greatly improved uponJohn Kerry's performance fromfour years earlier. As of the2024 presidential election^[update], this is the last time a Democrat won more than 40% of the vote in South Dakota, the closest a Democrat has been to winning the state since1996, the last time the victory margin was within single digits and the last time in whichBrown County,Lake County,Miner County,Minnehaha County,Moody County, andBrookings County voted for a Democratic presidential candidate.^[1]. This was also the last election in which South Dakota was regarded a swing state by some outlets.

• 2008 South Dakota Democratic presidential primary

There were 16 news organizations who made state-by-state predictions of the election. Here are their last predictions before election day:

McCain won two pre-election polls, and never polled less than 47%. The highest Obama ever polled was 50%; the final poll showed McCain leading 50% to 42%.^[15]

John McCain raised a total of $287,533 in the state. Barack Obama raised $337,053.

Obama and his interest groups spent $639,435. McCain and his interest groups spent just $1,531.^[16] Obama did not visit the state, while McCain visited once, going toSturgis.^[17]

South Dakota, a predominantly Republican state, has not voted for a Democratic presidential nominee sinceLyndon B. Johnson won the state in the landslide election of1964. A sparsely populated state whose population largely tends towards arural andconservative lifestyle, the state has been won by the Republicans in every election since then, usually by wide margins.

McCain was able to keep South Dakota in the GOP column in 2008, taking in 53.16% of the total statewide vote over Obama who received 44.75%, an 8.41-percent margin of victory. This margin of victory was considerably smaller compared to 2004 whenGeorge W. Bush carried South Dakota with 59.91% of the vote overJohn Kerry who received 38.44%, a 21.47% margin of victory, resulting in a 13.06% swing to the Democrats in 2008.

While McCain did well throughout the state, his main strength was in Western South Dakota, where he often won by landslide margins.^[18] He was able to carryPennington County, which contains the state's second largest city ofRapid City. In contrast, Obama ran best in Eastern South Dakota, losing most counties by fairly close margins. He also did well amongNative Americans; in Western South Dakota, the only counties Obama won were majority Native American.

Obama was able to substantially improve upon John Kerry's showing in South Dakota in 2004 by a number of factors. First, it helped that South Dakota received media attention during the course of the 2008 Democratic Primary, being the last state to vote in the historic and contentious primary that gaveHillary Rodham Clinton an 11-point victory over Obama; it was Clinton's last victory in the primary. In the general election, Obama was able to cut the margin significantly by narrowly carryingMinnehaha County, which contains the state's largest city ofSioux Falls. He was also able to winBrown County, which containsAberdeen, as well asBrookings County which containsBrookings, home ofSouth Dakota State University. He did much better than Kerry in Eastern South Dakota, which is where most of the people live, but McCain's margins throughout the state were too large to overcome.

During the same election, incumbent DemocraticU.S. SenatorTim Johnson wassoundly reelected over RepublicanState Senator Jim Dykstra, receiving 62.49% of the vote to Dykstra's 37.51%. At the state level, Democrats made gains in theSouth Dakota Legislature, picking up four seats in theSouth Dakota House of Representatives.

• Brown (largest city:Aberdeen)
• Lake (largest city:Madison)
• Marshall (largest city:Britton)

South Dakota has only one congressional district because of its small population compared to other states. This district, called the at-large district because it covers the entire state, is equivalent to the statewide election results.

Technically the voters of South Dakota cast their ballots forelectors, representatives to theElectoral College. The state is allocated three electors because it has onecongressional district and 2senators. All candidates who appear on the ballot or qualify to receive write-in votes must submit a list of three electors, who pledge to vote for their candidate and the candidate'srunning mate. In the state'sFirst Past the Post (plurality voting) system, the winner of a plurality of votes in the state is awarded all three electoral votes. Their chosen electors then vote for president and vice president. Although electors are pledged to their candidate and running mate, they are not obligated to vote for them.^[20] An elector who votes for someone other than his or her candidate is known as afaithless elector.

The electors of each state and theDistrict of Columbia met on December 15, 2008, to cast their votes for president and vice president. The Electoral College itself never meets as one body. Instead the electors from each state and the District of Columbia met in their respective capitals.

The following were the members of the Electoral College from the state. All 3 were pledged toJohn McCain andSarah Palin:^[21]
