Three Angles on Missouri Senate Politics

Josh Hawley Profile

Populist Intellectual with Presidential Ambitions

Josh Hawley's biography reads unlike most politicians at his level. He graduated from Stanford and Yale Law, clerked for Chief Justice John Roberts, and became Missouri attorney general at 37. Yet he built his political brand on attacking elite institutions — universities, tech companies, financial firms, and the professional class generally. His 2021 book "The Tyranny of Big Tech" argued for antitrust action against Silicon Valley. His 2023 book "Manhood" argued that American institutions had failed men, a populist-conservative culture-war framing. This intellectual populism sets him apart from typical Senate conservatives and points toward a future presidential run.

His fist-raised gesture toward crowds gathering outside the Capitol on January 6, 2021, followed by his objection to electoral vote certification, generated enormous criticism and a brief Simon & Schuster book deal cancellation. But it also cemented his position as the Senate's leading MAGA intellectual — a role he has leveraged for fundraising and national profile. Missouri's R+18 lean makes him invulnerable at home regardless of national controversy.

The McCaskill Era: How Missouri Flipped

From Competitive Battleground to Republican Lock

Missouri was a genuine swing state as recently as 2008, when John McCain won it by less than 4,000 votes — the closest presidential result in state history. Claire McCaskill's Senate tenure (2007-2019) demonstrated that a Democrat with exceptional local skills and careful positioning could survive in a state drifting Republican. She won in 2006 in a Democratic wave year, and won again in 2012 partly because Republican Todd Akin made disqualifying comments about rape and pregnancy that obliterated his campaign. Her 2018 defeat was the true end of competitive Senate politics in Missouri.

The underlying demographic explanation: Missouri's white working class without college degrees shifted dramatically toward Republicans in the 2016-2020 period, and there are not enough college-educated suburbanites in St. Louis and Kansas City to compensate. Unlike Georgia or Arizona, Missouri's urban centers are not large enough relative to the state's rural population to drive Democratic competitiveness. Without a McCaskill-caliber candidate and a catastrophic Republican implosion, no Democrat can win a Missouri Senate seat in the current electoral environment.

Eric Schmitt: Missouri's Other Senator

Attorney General Turned Senator, Hawley's Ideological Peer

Eric Schmitt won Missouri's open Senate seat in 2022 after serving as state attorney general. As AG, he built a national profile as an aggressive Republican litigator — suing the Biden administration over vaccine mandates, immigration policy, Title IX rules, and numerous other federal actions. He also sued China over the COVID-19 pandemic, a performative but nationally visible act that drove fundraising. His lawsuit count was one of the highest of any Republican AG in the country.

In the Senate, Schmitt has continued the combative-conservative positioning that won him national attention as AG. He is up for re-election in 2028, giving him a full six-year term to build profile. With both Hawley and Schmitt representing Missouri as ideologically aggressive populist conservatives, the state's Senate delegation has shifted from the old Blunt/Bond tradition of insider dealmaking toward an outsider-insurgent style that plays well with Missouri's current Republican base.
