After moving to Maryland in 1960, Goldwater became active in local politics, initially through her children's PTA and later being elected president of the Women's Suburban Democratic Club.[1][2][3] She was first elected to the Maryland legislature in 1974, and as a freshman delegate, she was one of the first two women to be appointed to the Appropriations Committee.[1] She later ran unsuccessfully for Maryland Senate and served in the administration of Governor William Donald Schaefer as a health policy adviser.[3] In that position, she helped to start the Governor's Wellmobile Program, operated by the Maryland School of Nursing.[1] At the conclusion of Gov. Schaefer's second term, Goldwater ran again for the District 16 Delegate seat,[4] returning to the House of Delegates in 1995.[3] As a legislator, Goldwater was known for her healthcare advocacy;[1] she also supported the Intercounty Connector and opposed slot machines.[3]
