2006 United States Senate election in North Dakota

The 2006 United States Senate election in North Dakota was held on November 7, 2006, to elect a member of the United States Senate to represent the state of North Dakota. Incumbent Democratic-NPL U.S. senator Kent Conrad won re-election to a fourth term. This was one of five Democratic-held Senate seats up for election in a state that George W. Bush won in the 2004 presidential election. As of 2026, this is the last time where either party won every county for the Class 1 Senate seat in North Dakota. == Democratic primary == === Candidates === ==== Nominee ==== Kent Conrad, incumbent U.S. senator (1992–2013) === Results === == Republican primary == === Background === Popular Republican governor John Hoeven was heavily recruited by prominent national Republicans, including Karl Rove and Dick Cheney to run against Conrad.
