Assessments
Onder's first House term began in 2025 after the 2024 federal campaign. During that same term, he voted for H.R. 28, the Protection of Women and Girls in Sports Act of 2025, which directly matched the promise and passed the House. However, the bill did not become law after failing to advance in the Senate. A same-term presidential executive order and later Supreme Court ruling advanced policy outcomes consistent with the promise, but those were not Onder-authored enactments and do not justify full candidate delivery. Overall, the promise was materially advanced but not fully delivered as a federal legislative accomplishment by Onder.
Onder can claim some same-term progress because he voted for House passage of H.R. 28, the Protection of Women and Girls in Sports Act of 2025, which directly matched the promise to protect women’s sports. But the bill only passed the House and stalled in the Senate, so no federal policy outcome was actually delivered. Because his documented contribution here is support for a relevant measure rather than a completed enactment, this is partial credit rather than full delivery.
