Who is my U.S. representative in OH-01?
Your current U.S. Representative for Ohio's 1st District is Greg Landsman (D), who has represented OH-01 since January 2023. The district covers the Cincinnati area, including all of Warren County and parts of Hamilton and Clinton counties. A couple of things worth noting: Redistricting: Ohio redrew its congressional map in October 2025 ahead of the 2026 elections, and the new boundaries — which made OH-01 somewhat more Republican-leaning — take effect after the November 2026 election. So Landsman is currently your rep, but district lines may shift depending on your exact address. 2026 election: Landsman is running for another term and faced a primary challenge from Damon Lynch IV in the May 2026 primary (which he'd have needed to win to be on the November ballot). The general election is November 3, 2026, and the district is considered highly competitive. 10TV 10TV If you want to double-check you're actually in OH-01 under the current map (versus a neighboring district), the House Clerk's "Find Your Representative" tool or GovTrack can confirm based on your exact address.

Correctly identifies Greg Landsman (D) as the OH-01 representative matching ground truth, but includes inaccurate district geography (OH-01 covers Hamilton and Warren counties, not Clinton) and speculative/possibly fabricated details about a 2026 primary challenger.
