Republican incumbent Mike Carey holds a structural edge in Ohio’s 15th congressional district ahead of the November 3, 2026 general election. The seat carries an R+5 partisan voting index, and Carey secured the Republican nomination following the May 5 primaries with minimal opposition. Democrat Don Leonard emerged from his party’s contest but faces an uphill path in a district where Republican candidates have consistently performed well in recent cycles. Trader consensus pricing the Republican outcome near 78% aligns with the incumbent’s name recognition, fundraising position, and the district’s underlying partisan lean, though a handful of mid-2026 surveys have shown Leonard closing the gap in head-to-head matchups. No major late-breaking developments have altered the race’s fundamentals since the primaries.
