2018 Oklahoma House Election Interactive Map

All US House seats to be contested in 2018

Oklahoma has five congressional districts; four of which are held by Republicans. There is one vacancy in OK-1. In lieu of a special election, the winner of the general election for that district in November will be appointed to serve out the remainder of this term. Ignoring the vacancy, Oklahoma is the state with the largest number of districts under 100% Republican control. OK-5, which includes Oklahoma City, is the only one that has a chance to become competitive.
