The Cook Political Report has moved the Kansas Senate race from “lean Republican” to “toss-up.” It is the most competitive the seat has been in decades.

Republican Senator Roger Marshall faces Democrat Adam Hamilton. Kansas has not elected a Democrat to the Senate since 1932, when George McGill won re-election. He left office in 1939. That is 94 years of Republican control.

Hamilton, 62, is a megachurch pastor who leads Resurrection, a large United Methodist church in the Kansas City area. He switched parties to run. A New York Times/Siena poll found the two candidates tied among likely voters.

Marshall, an obstetrician, won by double digits in 2020. He has faced criticism over reports that he sued about 700 patients over unpaid medical bills, leading to 81 arrests, according to the New York Times. He called the reporting a “hit job.”

Two former Republican governors, Mike Hayden and Bill Graves, have endorsed Hamilton. The Senate Leadership Fund now plans to spend millions defending the seat.

Cook also moved North Carolina toward Democrats and New Hampshire to “lean Democrat.” The shifts point to a tough midterm map for Republicans.
