The 1998 United States Senate election in Vermont was held November 3, 1998. Incumbent Democratic U.S. Senator Patrick Leahy won reelection to a fifth term.
Notably, the Republican nominee, dairy farmer and actor Fred Tuttle, withdrew from the race and endorsed Leahy, asking Vermonters to vote for his Democratic opponent because he hated Washington, D.C. and he was, as his wife had previously said publicly, unqualified to serve as a United States Senator. His campaign, which had been conducted primarily from his front porch in Tunbridge, Vermont, spent only $251 during the election season and featured the slogans "Spread Fred!" and "Why Not?". In spite of this, Tuttle still received 48,051 votes, or 22% of the total.
