In 2010, when incumbent State Representative Faye B. Culp was unable to run for re-election in the 57th District, based in Hillsborough, due to term limits, Young ran to succeed her in the Republican primary. She faced C. Todd Marks and Dan Molloy, whom she was able to defeat comfortably, winning 55% of the vote. In the general election, Young encountered Stacy Frank, the Democratic nominee. The two sharply disagreed on any number of issues, including the United States embargo against Cuba, which Young supported and Frank opposed; the Patient Protection and Affordable Care Act, which Frank supported and Young opposed; and, which Frank called "unconscionable," but which Young supported, noting, "Regardless of party affiliation, I think that we all agree that the best scenario for a child is to be in a loving family with a mother and father." In the end, Young ended up defeating Frank with 56% of the vote. When Florida House of Representatives districts were reconfigured in 2012, Young opted to run in the newly created 60th District, which included most the territory that she had previously represented in the 57th. In both the primary and the general election, she had no opponent, and won her second term entirely uncontested. Following the resignation of Jennifer Carroll, the Lieutenant Governor of Florida, Young was named by Governor Rick Scott as Carroll's replacement on the Florida Defense Support Task Force, which is "charged with enhancing and protecting Florida's military missions and installations." In this capacity, Young took a strong stance in favor of acquiring land adjacent to MacDill Air Force Base, as it "could be used for residential development incompatible with base operations," which could potentially "threaten MacDill Air Force Base's ranking in the next round of base closures" by the Base Realignment and Closure Commission. In 2014, Young was re-elected to her third term in the legislature without opposition.
Senate
Young ran for the Florida Senate in 2016 after court-ordered redistricting created an open seat in western Hillsborough County in 2016. She defeated Democrat Bob Buesing and independent Joe Redner in the general election, 48% to 41% to 10%. She will likely be defending her seat in 2018, which might be at risk. In 2018, Young sought reelection. She was challenged by Democratic state Representative Janet Cruz. Cruz defeated Young by 326 votes.
