Mary Gay Scanlon

She transferred to the 5th District in January 2019, with two months more seniority than the other freshmen elected in 2018.

On February 25, 2018, Scanlon launched her campaign for US Congress in Pennsylvania's 5th District in the 2018 election. The district had previously been the 7th, represented by four-term Republican Pat Meehan, who had announced a month earlier that he was not running for reelection. She kicked off the campaign by giving a speech at Swarthmore Rutledge School. The seat was one of several that had been significantly redrawn by the Pennsylvania Supreme Court, which ruled that the previous map had been an unconstitutional partisan Republican gerrymander. The redrawn 5th covers all of Delaware County, a sliver of Montgomery County, and the southwestern corner of Philadelphia. Scanlon said that her interest in running was also piqued by the fact that Pennsylvania had no women in its congressional delegation. She was endorsed by former Pennsylvania governor Ed Rendell and the Philadelphia Inquirer.

Meehan resigned from the House on April 27, 2018, a month before the primary. Scanlon was named the Democratic candidate in a special election to succeed him. As a result, she ran in two elections on November 6, a special election for the balance of Meehan's fourth term in the old 7th and a regular election for a full two-year term in the new 5th. Her Republican opponent was prosecutor Pearl Kim.

She was sworn into her 7th district seat on November 13, 2018, in a ceremony attended by Hawa Salih, a Sudanese human rights activist whom Scanlon helped gain asylum in the U.S. She was one of four Democratic women elected to Congress from Pennsylvania in 2018. The others were Madeleine Dean, Chrissy Houlahan and Susan Wild. The state's congressional delegation had previously been all male.

On May 15, Scanlon won the 10-person primary with 16,831 votes, or a 28.4% share of the votes cast. Her closest competitor was Ashley Lunkenheimer, who received 9,060 votes or a 15.3% share. "Tonight we can revel in this moment," Scanlon said in her acceptance of the Democratic nomination. "You all here have once again rewritten history in Delaware County. Tonight, we made it possible for this new district for the first time to be represented by a Democrat in Congress and to be represented by a woman in Congress." The new 5th is more compact and Democratic than its predecessor. Had it existed in 2016, Hillary Clinton would have won it with 63% of the vote, which would have been her third-best performance in the state and her strongest outside of the Philadelphia-based districts. By comparison, Clinton won the old 7th with 49% of the vote.

In 2006, she was appointed vice chair of the Tax Commission. The following year, she joined the board of the Wallingford-Swarthmore School District and served as its President from 2009 to 2011. She continued as a member of the board until 2015.

In 1985, Scanlon represented a sexually abused 11-year-old girl in a dependency case. This experience made Scanlon decide to pursue a career in public interest law. In 1994, she received the Fidelity Award, the highest award for public service from the Philadelphia Bar Association.

Scanlon earned her bachelor's degree from Colgate University in 1980 and her Juris Doctor from the University of Pennsylvania Law School in 1984. Upon completing her education she became a judicial clerk for the Superior Court of Pennsylvania.

Scanlon was born in Syracuse, New York but was raised from age 6 in Watertown, New York. She is the daughter of Daniel J. Scanlon Jr. and Carol Florence Yehle, and has two sisters, Elizabeth Maura Scanlon and M. Kathleen Scanlon. Her father was an attorney and was appointed part-time magistrate in 1971 and full-time magistrate in 1993. Her maternal grandfather, Leo J. Yehle, was a family-court judge who helped write the first juvenile justice code in New York in the 1960s.
