Member of Congress · 119th Congress
Robert F. Onder, Jr.
Robert Onder is a Republican U.S. representative from Missouri, in Congress since 2025, who voted with most Republicans on 94% of the 119th Congress’s yes/no votes.
How we count: “Broke with party” is a yes/no roll call where the member voted against most of their own party on that vote (party as recorded; even splits not counted). “Pork: own share” splits each earmark shared by several members evenly among them.

Read this first. These are counts of records Congress.gov lists. Many bills never get a CBO estimate or a report, so a zero is not a mark against a member. We never show this as a score.
