In 1992, Stefanics ran for the New Mexico Senate in the 39th district, a mostly rural district covering parts of six counties in northern New Mexico. She won the seat and took office in January 1993. During her four years in the senate, she co-chaired the Health and Human Services Interim Committee. In her race for re-election in 1996, she faced a primary challenge from Phil Griego, a former member of Santa Fe City Council. She lost the primary election by a margin of 54 votes and Griego went on to win the seat. In 1998, she ran for a seat on the newly created Public Regulation Commission from the 3rd district. In the primary election held on June 2, 1998 she faced fellow Democrat Jerome Block. The race was extremely close and Stefanics originally appeared to have won but final results, which included a number of originally uncounted ballots from Rio Arriba County, showed Block winning by approximately 0.2%. He went on to win the general election handily. In 2000, she mounted a rematch against Griego, aiming to win back the seat she'd previously held in the state senate. She lost the primary by 53% to 47%. Nearly 15 years after losing to Greigo, Stefanics announced in September 2015 that she would run again for the state senate in the 39th district.
Executive appointments
Stefanics spent several years as the director of the New Mexico Health Policy Commission, a post to which she was appointed by Governor Bill Richardson. She had previously spent three years as deputy secretary of the state Human Services Department.
County Commission
In 2008, Stefanics mounted a bid for the Santa Fe County Commission from the 5th district, which covers Eldorado and the Community College District south of the city. She won the Democratic primary election convincingly, garnering 52% of the vote in a five-way race. She was unopposed in the general election and took office on January 1, 2009. Stefanics was up for re-election in 2012 but drew no opponents in either the primary or general elections. She can not run again due to term limits.
Personal life
Stefanics is a lesbian and was the first openly gay person to serve in the New Mexico Legislature. She has spent almost two decades with her partner, Linda Siegle, a former chairman of the Santa Fe Community CollegeBoard of Trustees. Her campaigns have often won the support of the Gay & Lesbian Victory Fund. On August 23, 2013, Stefanics and Siegle became the first same-sex couple in Santa Fe County to receive a marriage license as issued by the county clerk.
