 Larson was elected House Democratic Caucus Vice Chairman in 2006, and became Caucus Chairman at the start of the 111th United States Congress; he served in the latter role for four years before leaving that role due to term limits.Larson's victory resurrected a political career temporarily suspended by a crushing defeat in the 1994 Democratic primary for Governor, in which he lost to comptroller Bill Curry despite receiving the endorsement of the state party convention.Larson won election in 1998 with 58% of the vote and has been reelected ever since, receiving no less than 60% during each election cycle.
