U.S. senator before election Kent Conrad Democratic–NPL Elected U.S. Senator Heidi Heitkamp Democratic–NPL

Though each party endorses a single candidate in state conventions in the spring, ballot access for the general election was determined in a primary election held on June 12, 2012.^[2]

Heidi Heitkamp, a Democratic-NPL former North Dakota Attorney General, won the open seat over Republican Rick Berg, North Dakota's at-large U.S. Representative, by a margin of 0.9%.^[3] Heitkamp outperformed President Barack Obama by 20.5%, the latter having lost North Dakota by 19.6% in the concurrent presidential election.^[4] Heitkamp's very narrow winning margin made it the closest race of the 2012 United States Senate elections. The victory made Heitkamp the first woman ever elected to Congress from North Dakota.^[a]

As of 2024^[update], this was the last time a Democrat won a federal and/or statewide election in North Dakota.^[5]

Democratic-NPL primary

The North Dakota Democratic-NPL Party held their state convention March 16–18, 2012, in Grand Forks. Former state attorney general and 2000 Democratic gubernatorial nominee Heidi Heitkamp was uncontested in seeking the official party nomination and was the only member of the party elected to appear on the state primary ballot.^[6]
