Academic Singer was a professor at
Haverford College from 1991 to 2002, where she earned tenure. She experienced
sexual harassment while at the school, which she discussed in a 2017 article in
The Chronicle of Higher Education. She founded Campaign Scientific, which provided data services to political organizations and businesses. In 2002, she began requesting data from the
Office of the Philadelphia Commissioners, which is responsible for conducting elections in the city, to post the data on an unofficial website for the city's Democratic party. The commission would only provide data in paper form until Singer threatened to sue them in 2008. In 2011, she was elected as a
Philadelphia City Commissioner, defeating 36-year incumbent
Marge Tartaglione. She ran an aggressive campaign, describing her opponent as "an embarrassment". Her campaign was endorsed by the
Philadelphia Daily News and
John Dougherty and his IBEW Local 98. She was sworn into office on January 3, 2012. The day after the city's handling of the November 6, 2012 elections led to criticism of the commission, Schmidt and Clark voted to remove Singer as chair of the commissioner and appoint themselves as co-chairs.
The Philadelphia Inquirer reported that the removal did not appear related to the election, however, and noted that the commissioners "had been bickering for months at their weekly public sessions over seemingly small issues" as well as Singer's vocal opposition to the state's new
voter ID law. Singer's reelection attempt in 2015 was challenged by three Democratic voters for failing to obtain the required 1,000 signatures on nomination petitions, falling four short. Her term as city commissioner ended in 2016. In October 2018, Singer launched a
podcast entitled
Defend Democracy! where she reflects on her experience as a former election official, data strategist, and successful candidate, with advice to those who have interests in entering politics. ==Personal life==
