Split-ticket districts in the 2016 presidential and U.S. House elections
In 2016, 35 U.S. House districts voted for the presidential candidate from a different party from the U.S. representative it elected. Twenty-three districts voted for a Republican representative and Hillary Clinton (D). Twelve districts voted for a Democratic representative and Donald Trump (R).[1]
With 8 percent of districts splitting between the parties, the 2016 election had the sixth fewest split districts since 1904. Read more about the historical context of split districts here.
A redrawing of the Pennsylvania congressional map in February 2018 added two more Republican/Clinton districts, bringing the total to 25. Conor Lamb's (D) win in a March 2018 special election for Pennsylvania's 18th Congressional District added one more Trump/Democratic district, bringing the total to 13.
