2018 Kansas elections

Kansas elected four U.S. representatives, one for each congressional districts. In 2018, the delegation's Republican majority changed from 4–0 to 3–1, the first time Democrats have held a seat in the state since 2010.

Incumbent Republicans Jeff Colyer and Tracey Mann lost their party's renomination in a tight primary election won by Secretary of State Kris Kobach and businessman Wink Hartman by a margin of around 0.1 percent.[1] Democrats nominated state senators Laura Kelly and Lynn Rogers, with businessman Greg Orman and state senator John Doll joining the race as independents.[2] Polls leading up to the election had Kobach and Kelly running close, leading to many news outlets predicting a tossup election.

Kelly won the election, beating Kobach by five percentage points. Kelley became the oldest governor in Kansas history, taking office at the age of 68.[3]
