Daniel William Lipinski (born July 15, 1966) is an American politician and political scientist who has served as the U.S. Representative for Illinois’s 3rd congressional district since 2005. His father, Bill Lipinski, held the seat from 1983 to 2005. The district encompasses parts of southwestern Chicago as well as much of its southwestern suburbs.
Lipinski worked for a number of politicians, including U.S. Representatives George E. Sangmeister, Rod Blagojevich and Dick Gephardt, and Cook County State’s Attorney Richard A. Devine. He has a PhD in political science from Duke University. He taught at the University of Notre Dame from 2000 to 2001 and at the University of Tennessee from 2001 to 2004. In 2004 Lipinski’s father won the Democratic primary for Illinois’s 3rd congressional district, where he was the incumbent, and shortly afterward retired. Upon his retirement, the state Democratic Party chose the younger Lipinski to replace his father on the ballot. Lipinski defeated his Republican challenger in this heavily Democratic district in the general election.
Lipinski has a reputation as one of the most conservative Democrats in the House. Lipinski did not endorse President Barack Obama for reelection in 2012, opposes legalized abortion and stem cell research, was the only House Democrat from Illinois to vote against the Affordable Care Act, supported reauthorizing the Patriot Act in 2006, and supported the Defense of Marriage and First Amendment Defense Acts.
