Incumbent Roger Marshall (R), Adam Hamilton (D), and David Graham (L) are running in the general election for U.S. Senate in Kansas on Nov. 3.

This U.S. Senate race is among several that will help determine which party controls the chamber. Heading into the election, Republicans have a 53-45 majority. AP's John Hanna writes, "Republican-leaning Kansas has a sizable bloc of moderate voters, protects abortion rights and regularly elects Democratic governors. But Democrats haven’t come within 10 points of winning a Senate race in more than 50 years, and they haven’t won one since 1932."

According to The Cook Political Report, which rates the election a Toss-up, three factors make the race competitive this year: "[A] stronger-than-expected Democratic challenger who has a moderate message and credentials; an incumbent who was slow to wake up to the real threat both his opponent and the environment pose; and erosion in Trump’s support on the ground rooted in the agriculture economy’s struggles over high fuel and fertilizer prices and distrust over beef imports."

Marshall has served in the U.S. Senate since 2021. He previously represented Kansas' 1st Congressional District from 2017 to 2021. Marshall is a former obstetrician-gynecologist and veteran of the U.S. Army Reserves. Marshall says, "Here’s what I’ve fought for: permanent bonus depreciation so farmers can afford their equipment, higher estate tax exemptions so family operations can pass to the next generation, stronger crop insurance, and clean fuel tax credits that expand markets for Kansas corn and soy. Kansas farmers feed this country. They deserve a Senator who shows up, listens, and fights for them every single day." President Donald Trump (R) endorsed Marshall.

Hamilton is the founder of the largest United Methodist church in the country. He says, "People are struggling to pay for gas, groceries, housing, and especially health care. I'll work to bring those costs down: end the self destructive policies coming out of Washington like tariffs and war, crack down on the price-gouging and anti-competitive behavior that push up your bills to pad profits, get more homes built that working families can afford, and push for trade and tax policies that help Kansas families, farmers, and small businesses instead of making fertilizer, diesel, groceries, and everyday necessities more expensive." Former Kansas governors Bill Graves (R) and Mike Hayden (R) endorsed Hamilton.
