In the regularly scheduled election in November 2004, freshman incumbent Stephanie Herseth and state Senator Larry Diedrich, who had run in the July 2004 special election earlier, faced each other in a rematch; Libertarian candidate Terry L. Begay also ran in this election.

Herseth again prevailed, this time by a wider margin of 53% to 46%, despite President George W. Bush's dominant 59.9% to 38.4% over Senator John Kerry in South Dakota in the 2004 presidential election, as well as Senate Democratic Leader Tom Daschle's narrow loss in the state's concurrent election for U.S. Senate.
