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.

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.
