In the 1995 general election, Gautreaux defeated the Democrat-turned-Republican Joe Harrison, 8,457 votes (69 percent) to 3,809 ballots (31 percent). Harrison was subsequently elected in 2007 to House District 51 and still holds the seat. Background Gautreaux attended Nicholls State University in Thibodaux, Louisiana.
