The 1998 United States House of Representatives election in Vermont was held on Tuesday, November 3, 1998, to elect the U.S. representative from the state's at-large congressional district. The election coincided with the elections of other federal and state offices, including an election to the U.S. Senate.
Candon won the primary against Long by a comfortable 16-point margin. His victory came of the back of a very strong result in Rutland County, where he received over 90% of the vote, while also keeping Long's margin of victory in Chittenden County down to 15%.[4] Diamondstone's effect on the primary was disputed; Long believed that Diamondstone had drawn voters from his campaign while Candon stated that he did not believe Diamondstone had a notable effect on the results.[4]
