Candidates clash over Trump policies, Senate control in debate

What happened: Kansas Sen. Roger Marshall and Democratic challenger Adam Hamilton debated Wednesday in a race that could decide Senate control. Marshall warned a loss could hand the chamber to Democrats; Hamilton distanced himself from mainstream Democrats. Key numbers: At least 100 Kansas Republican leaders have endorsed Hamilton. Why it matters: Polling suggests a tight race, and millions of dollars have flooded the state's airwaves with ads against both candidates. The race could hinge on how many Republicans cross party lines to vote for Hamilton.
