Democrats have a 232-197 advantage over Republicans in the U.S. House of Representatives. There is one independent member, and there are five vacancies. Currently, if Republicans win 18 Democratic-controlled districts in the November general election, they will win control of the House. If Democrats hold as many districts, they will maintain their control of the chamber.
