According to the APM Research Lab's Voter Profile Tools[4] (featuring the U.S. Census Bureau's 2019 American Community Survey), the district contained about 559,000 potential voters (citizens, age 18+). Of these, 80% are White, 10% Black, and 6% Latino. Immigrants make up 5% of the district's potential voters. Median income among households (with one or more potential voter) in the district is about $67,300, while 9% of households live below the poverty line. As for the educational attainment of potential voters in the district, 9% of those 25 and older have not earned a high school diploma, while 30% hold a bachelor's or higher degree.
Prior to 2019, the district was located in the northeastern part of the state. TheSupreme Court of Pennsylvania redrew the district in 2018 after ruling the previous map unconstitutional because ofgerrymandering. The court addedState College to the old district's boundaries while removing someDemocratic-leaning areas and redesignated it thetwelfth district; an area encompassing Harrisburg and York was numbered as the 10th. The new 10th district is represented byRepublicanScott Perry, who previously represented the oldfourth district.[5]
The district was one of the 12 original districts created prior to the4th Congress. In 2006, when it was still located in northeastern Pennsylvania, the 10th district experienced one of the greatest party shifts among all House seats that switched party control: in 2004, RepublicanDon Sherwood won with an 86% margin of victory over his nearest opponent and two years later, DemocratChris Carney unseated Sherwood by a 53%–47% margin.[6] In 2008, Carney won reelection by 12 points but the district swung back in 2010, electing RepublicanTom Marino. The district was mostly Republican in its political composition, an aspect of the district that was reflected especially well in presidential elections. In 2004, PresidentGeorge W. Bush won 60 percent of the vote in the district and in 2008, SenatorJohn McCain beat SenatorBarack Obama here by a margin of 54 percent to 45 percent. Nonetheless, Carney easily won reelection as a Democrat the same year McCain won the district. However, in the 2010 midterm elections, Marino unseated Carney by a 55%–45% margin. In 2016, local businessman and former mayor ofLewisburg, Mike Molesevich challenged Marino for the seat, but he fell to the Republican in November by more than two to one. In 2018, Marino won election to a redrawn 12th district; while he remained the congressman for the 10th district into January 2019, he moved within the new district's boundaries beforehand.
