US Midterms 2026: Mentioned in: Ohio's Brown outraises Husted 6 to 1Background
Josh Mandel is the Republican Sherrod Brown beat in 2012, and that race is the parallel for Brown's 2026 bid in Ohio's special Senate election against Jon Husted, who was appointed to the seat JD Vance left to become vice-president. Brown again faces outside spending, with America PAC reporting $2.59m against him in the third quarter of 2026.
Mandel served in the Ohio House from 2007 to 2011 and as Ohio treasurer from 2011 to 2019. In 2012 Brown beat him by about six points despite tens of millions of dollars of outside spending against Brown. Mandel sought the Senate nomination again in 2022 and lost the primary to JD Vance.
His 2012 loss is the evidence that outside money alone did not unseat Brown before.
