An avid Democrat and leading voice on environmental issues, Moffett first appeared on the national scene in the 1970s as an environmental activist and coalition-builder in his home state of Connecticut. Moffett served as Director of the Office of Students and Youth in the Office of Education within the Department of Health, Education, and Welfare from 1969 to 1970, but quit to protest the Vietnam War. On April 10, 1975, Moffet walked out of the House chamber during President Ford's State of the World speech when he requested military aid for Vietnam. Aligned with consumer activistRalph Nader, Moffett founded the Connecticut Citizen Action Group and parlayed this to a victory in 1974 for the seat vacated in the U.S. House of Representatives for Connecticut's 6th congressional district seat when Ella T. Grasso ran for Governor. Moffett held the northwestern Connecticut seat until 1982. He was regarded as a liberal and an opponent of the oil industry. He was also closely aligned with trade unions. Moffett served as chairman of the House Subcommittee on Energy, Environment, and Natural Resources. In 1981, he was selected to be one of the first Young Leaders of the French-American Foundation. In 1982 Moffett challenged U.S. Senator Lowell Weicker. While 1982 was a strong year for Democrats nationwide, Weicker was considered a moderate/liberal Republican and defeated Moffett 52-46 percent. Moffett's protégé, liberal State SenatorBill Curry also lost the 6th district seat to RepublicanNancy Johnson. Moffett attempted a political comeback in 1986 seeking to gain the Democratic nomination over incumbent Governor William O'Neill. That effort failed. Moffett later was a broadcaster on WVIT Channel 30 in Hartford. Moffett's final comeback effort was in 1990 when he moved to the town of Newtown to seek election to the open congressional seat in Connecticut's 5th congressional district, which was being vacated by John G. Rowland, who was running for governor. Moffett's opponent, WaterburyaldermanGary Franks claimed that Moffett was far too liberal to represent conservative 5th district voters, and Franks won the election. In 2004 he broke with Ralph Nader regarding his independent candidacy for president. Moffett was among those who coordinated a national effort on behalf of the Democrats to deny votes and ballot access to the Nader campaign. He also recently criticized the independent campaign of Joe Lieberman.
