State representative In her first run for public office, Williams successfully ran for the
Pennsylvania House of Representatives from the
149th District. Williams narrowly defeated Sheehan in November by a margin of 506 votes, becoming the first Democrat to ever represent the district. During her tenure in the House, Williams founded and co-chaired the Children's Caucus, and introduced legislation to give businesses tax credits for donating services or equipment to libraries. She also advocated for increased education spending, and opposed
gun control legislation that was written by the
National Rifle Association. In 1998, Williams was re-elected to a second term after defeating Mary Wright, a former Lower Merion school board member, by a margin of 58%–42%. During the
2000 presidential primaries, she served as co-chair of
U.S. Senator Bill Bradley's campaign in Pennsylvania. In 2000, she defeated Republican Lynne Lechter for a third term, receiving 62% of the vote.
State senator in 2002 In 2001, longtime Republican incumbent
Richard Tilghman resigned from the
Pennsylvania State Senate, where he had represented the
17th District for thirty-two years. The district, covering parts of Montgomery and
Delaware Counties, is located in the
Philadelphia Main Line. Williams subsequently ran in the special election to fill the remainder of Tilghman's term, facing fellow State Representative
Lita Indzel Cohen. During the campaign, Williams ran on her moderate reputation and bipartisan record; she even received several Republican endorsements. Williams was sworn in on December 3, 2001. In 2004, she won re-election to a full term after defeating Republican Ted Barry, a Montgomery County assistant district attorney, by 64%–35%. She became known for her work on behalf of children, families, and the environment, and authored a law that allows women to publicly breastfeed their children. In 2010,
Politics Magazine named her one of the most influential Democrats in Pennsylvania, noting the value of receiving her endorsement. == Philanthropy and community engagement ==
