Suzan Kay DelBene (née Oliver; /ˌdɛlˈbɛneɪ/ DEL–BEH-nay;^[1] born February 17, 1962) is an American politician and businesswoman who has been the United States representative from Washington’s 1st congressional district since 2012.^[2]

DelBene was the 2010 Democratic nominee for U.S. representative for Washington’s 8th congressional district and narrowly lost to incumbent Republican Dave Reichert.^[3] In 2012 she won the general election in Washington’s redrawn 1st district against Republican John Koster,^[4][5] while simultaneously winning the election for the remainder of the term in the 1st district under the pre-2012 boundaries, a seat left vacant by the resignation of Jay Inslee.

DelBene chairs the Democratic Congressional Campaign Committee (DCCC) and is a former chair of the New Democrat Coalition.

DelBene was born in Selma, Alabama, the fifth child of Barry and Beth Oliver. At a young age, her family moved to Newport Hills in Bellevue, Washington. Later they moved to Mercer Island. In an autobiographical video, DelBene described her family’s trouble paying bills and the hardship they faced after her father, a longtime airline pilot, lost his job.^[6] After fourth grade, her family moved around the country in search of work.^{[citation needed]}

After graduating from The Choate School, a prep school in Wallingford, Connecticut, DelBene went to Reed College, where she earned a bachelor’s degree in biology. She then continued her education at the University of Washington, earning a master’s degree in business administration.^[7]

From 1989 to 1998 DelBene worked at Microsoft, where she was director of marketing and business development for the Interactive Media Group, marketing and sales training for Microsoft’s Internet properties, and other business development and product management roles with Windows 95 and early versions of Microsoft’s Internet Explorer Web browser. In 1998 she left to help found drugstore.com and serve as a vice president. In 2000, she became CEO of Nimble Technology,^[8] leading it through its acquisition by Actuate in 2003. In 2004, she returned to Microsoft as corporate vice president of the Mobile Communications Business until 2007.^[9] From 2008 to 2009, she was a management consultant and strategic advisor to Global Partnerships, a nonprofit supporting microfinance and sustainable solutions in Latin America.^[10][11] DelBene was named as the director for the Washington State Department of Revenue on November 30, 2010, replacing outgoing director Cindi Holmstrom.^[12]

In 2010 DelBene ran for the U.S. House of Representatives as a Democrat against the incumbent in the 8th congressional district, Dave Reichert, a Republican. According to DelBene’s campaign website, the economy was her top priority.^[13] She was endorsed by the Seattle Times and the Seattle Post-Intelligencer,^[14][15] as well as several Democratic politicians.^[16]

DelBene faced Reichert in the general election, after coming in 2nd in the primary voting. In Washington, the top two advance. She lost to Reichert in the general election on November 2. She was named Washington State Revenue Director by Governor Christine Gregoire on November 30.

DelBene ran for Congress again in 2012. She won the Democratic nomination for the redrawn 1st district, previously represented by Jay Inslee, which became more competitive due to redistricting. Inslee had resigned in March to focus on his campaign for governor.^[17] DelBene ran in two elections that day against Republican John Koster—a special election for the last two months of Inslee’s seventh term (held in the boundaries of the old 1st), and a regular election for a full two-year term. She defeated Koster in both, winning the special election with 60% of the vote and the regular election with 54%. Her victory margin in the regular election was wider than expected, considering^{[clarification needed]} that the district was about six points less Democratic than its predecessor.^[4][5] On November 13, she was sworn in as the district’s representative for the remainder of the 112th Congress,^[2] giving her a leg up in seniority over all but a few other representatives first elected in November 2012 for the 113th Congress.

DelBene spent $2.8 million of her own money in a race in which she raised over $4 million, in a Congressional race that became the most expensive in Washington state history.^[18]

DelBene defeated Republican nominee Pedro Celis^[19] with 55% of the vote.^[20]
