Four weeks before the midterms, the Cook Political Report shifted the rating of the U.S. Senate race in Kansas from 'Lean Republican' to a 'Toss Up'. This change occurred alongside shifts in New Hampshire and North Carolina toward the Democratic Party.
In Kansas, Republican Sen. Roger Marshall holds a slim 0.4% lead over Democrat Adam Hamilton. The rating change follows reports that Marshall sued hundreds of former patients for medical bills, resulting in numerous arrests.
