Kenyon was first elected to the House in 1986 from Orange County's 3rd house district (Bradford, Corinth and Vershire) with 827 votes to 534 for Republican Warren S. Sweet.[3] He was re-elected in 1988 and 1990, before being defeated in the 1992 general election by Republican Robert Spain (who drew 973 votes to Kenyon's 908) after a redistricting took Vershire out of the district; he failed to reverse that result in 1994, when the two faced each other once more; but in 1996, Kenyon reclaimed his seat from Spain, with 879 votes to Spain's 708. In 1998, Kenyon was unseated by Neil Randall, who was running as a Libertarian/Republican fusion candidate. Kenyon lost again in 2000 to Randall. In 2002, Bradford had been moved into a new 2nd Orange County district (Bradford, Fairlee and West Fairlee), and Kenyon defeated Randall with 858 votes to Randall's 642.[4] In 2004, Kenyon was defeated in the Democratic primary by Sarah Copeland Hanzas.[5]
