Huffman’s political career began in June 1977, when she was appointed to the Hillsboro City Council to replace resigned member Ted Clarno. She had been asked to join the council, and agreed to what she originally planned to be a short-term involvement in city government. This work included representing the city at official events as well as lobbying on behalf of the city. Huffman is credited with getting
MAX light rail extended to downtown Hillsboro from its originally planned terminus at
185th Avenue. Her lobbying included an episode when she spoke roughly to the head of the
Federal Transit Administration in a phone call ("I had to get a little stern with him," said Huffman), as well as trips to
Washington DC. The resolution was later passed by the city council. She had helped develop a similar resolution for a group representing the county and ten other cities, with both resolutions sent to a task force created by the
Oregon Legislature that was examining the role of Metro. Huffman traveled to
Fukuroi, Japan, in 1988 to sign an agreement that created a sister-city relationship with the Japanese city. Fukuroi officials had visited Hillsboro in June 1987. While mayor she served on the board of directors for the League of Oregon Cities, including one year as president of that organization in 1987. Huffman was mayor from 1985 to 1993. She was praised for her work on behalf of the city by other elected officials in Hillsboro. "I think her power lies in her ability to get people to agree without conflict; she defuses any situation and is able to make things happen," said councilman Jim Lushina, While she was mayor Hillsboro grew from around 29,000 residents to approximately 40,000. ==Later years==
