Koop is an outspoken defender of free enterprise. Her grandfather in 1929 established National Shoes in Dallas, the oldest family-owned business in the city. Four generations of her family worked there prior to its closure in the 1990s. She was formerly employed by the North Central Texas Council of Governments, Dallas Area Rapid Transit, and the North Dallas Chamber of Commerce. In the March 4, 2014 Republican primary for House District 102, Koop led the incumbent Stefani Carter, an African American, by 163 votes. She received 3,646 votes to Carter's 3,483. Two other candidates held another critical 32 percent of the ballots cast. One of the two eliminated candidates, Samuel Brown, endorsed Koop over Carter, who had first announced her candidacy for the Texas Railroad Commission but then decided to run for a third term in the House. Brown claimed that Carter told him her primary interest in running again was to collect a state pension which she could receive after two more terms in the state House, a contention Carter dismissed out of hand. In her runoff election campaign, Koop challenged Carter on the "trust" issue. Carter was originally seen as more conservative than Koop, whom she tried to cast as a Moderate Republican, who as a city council member until she was term-limited in 2013 had voted to place numerous bond issues on the ballot. Carter claimed that Koop had supported on the council $500 million in increased taxes. Koop nevertheless sought with considerable success to depict herself as more conservative politically than Carter. She stressed her support for border security and opposition to illegal immigration. On May 27, Koop unseated Carter, 5,072 to 3,405. In addition to border security, Koop outlined her key campaign issues as minimizing the impact upon Texas of the Patient Protection and Affordable Care Actsigned into law in 2010 by U.S. President Barack H. Obama, protecting the water supply of the greater Dallas area, and strengthening local schools. Koop vowed as a legislator to "fight every program and tax that hurts small businesses so we can grow our economy and create jobs." Koop carried the endorsement of the Dallas Morning News, former Dallas Mayor Tom Leppert, Tarrant County Judge Glen Whitley, Richardson Mayor Laura Maczka, and the Richardson Firefighters Association. In the general election held on November 4, 2014, Koop claimed the House seat by defeating the Republican-turned-Democrat, George M. Clayton, a retired school teacher and administrator, 20,394 to 12,243.
