[constituency_baseline] District summary: Missouri's 3rd Congressional District stretches from the St. Charles County suburbs of St. Louis westward through central Missouri, encompassing Jefferson City (the state capital), the southern half of Columbia (including the University of Missouri), and rural counties including Crawford, Gasconade, Montgomery, Osage and portions of Callaway. Home to approximately 780,389 constituents, the district is overwhelmingly White (85.6%) with small Black, Hispanic, and Asian minority populations. The median household income is $81,928 — more than double the $37,585 national median — with a low poverty rate of 6.1% (vs. 12.4% nationally). Homeownership is 74.7% (well above 65.5% nationally), median home value is $268,300, and median rent is $1,045. 35.4% of adults hold a bachelor's degree or higher (above the 33.7% national average), and the median age is 39.4. Only 0.2% of residents use public transit, and the average commute is 24.2 minutes. The economy is anchored by healthcare, state government (Jefferson City), higher education (University of Missouri-Columbia, Lincoln University), manufacturing, agriculture, and tourism centered on the Lake of the Ozarks. The district has a Cook PVI of R+27 and shifted 3 points more Democratic since the last redistricting, though it remains a safe Republican seat. Trump won the district by approximately 26 points in 2020. Onder succeeded retiring 8-term Republican Blaine Luetkemeyer, who defeated Onder in the 2008 primary. Onder won the 2024 general election with approximately 63% of the vote.

Voted yea on H.R. 29 (Laken Riley Act (119th Congress, January 7, 2025)) on 2025-01-07: Onder voted yea on mandatory ICE detention for undocumented immigrants accused of nonviolent crimes including shoplifting — the first bill of the 119th Congress. As a Missouri state legislator, Onder had sponsored the state's sanctuary city ban and legislation training the Missouri Highway Patrol to enforce immigration laws. During his 2024 campaign, he said: 'It is not our job as the United States of America to take everyone who doesn't get along with their government.' His MO-03 district is 85.6% White and overwhelmingly native-born, making this a politically safe hardline immigration vote. The bill passed 264-159 with 46 Democratic defections. All 217 House Republicans present voted yea.

Voted yea on H.R. 1 (One Big Beautiful Bill Act (OBBBA) — House final passage, July 3, 2025) on 2025-07-03: Onder voted yea on legislation the CBO projected would add $3.4 trillion to deficits and cut approximately $1 trillion from Medicaid and SNAP. He called it 'a huge win for the American people' and 'a clear affirmation of the America First agenda.' His MO-03 district has 6.1% poverty, median household income of $81,928, and thousands dependent on Medicaid and SNAP — particularly in rural counties like Crawford County, where 19% of residents are on Medicaid and nearly 15% face severe housing issues. The CWA gave him a 0% score for 2025, specifically citing this vote as imposing 'deep and damaging cuts to vital programs like Medicaid.' As a physician, his vote for massive Medicaid cuts directly contradicts the medical oath to 'do no harm.' Only 2 House Republicans voted nay. Onder subsequently defended the bill at a private meeting with business leaders while excluding constituents, and refused to hold public town halls where affected constituents could question him.

[disclosure] Onder refuses to hold in-person public town halls. He held a telephone town hall with 18 minutes' notice and a private, curated meeting with business leaders while excluding constituents. The Boone County Democrats held an 'empty chair town hall' to protest his absence. Constituents protested outside the private meeting, and a Crawford County editorial accused him of being 'afraid to meet with us.'

[vote] Onder voted yea on the OBBBA (H.R. 1) on both May 22 and July 3, 2025. The CBO projected the bill would add $3.4 trillion to the national debt over ten years and cut approximately $1 trillion from Medicaid and SNAP. Onder touted the bill as 'a huge win for the American people' that 'renews critical Trump-era tax cuts.' The CWA gave him a 0% score for 2025, noting the budget reconciliation 'imposes deep and damaging cuts to vital programs like Medicaid' while 'reward[ing] corporations that move jobs overseas.' After voting for the bill, Onder held only private meetings with business leaders — excluding constituents — and refused public town halls.

On March 23, 2026, he tweeted 'The people of #MO03... want Washington to confront our out-of-control national debt.' He also touted his right-to-work advocacy and limited-government philosophy as a Missouri state senator.
