Ohio treasurer Mandel wins GOP nomination for US Senate

Ohio Treasurer Josh Mandel will face U.S. Sen. Sherrod Brown in the fall.

COLUMBUS — Ohio Treasurer Josh Mandel has easily won the Republican nomination for U.S. Senate.

The 34-year-old Marine veteran prevailed in a six-way GOP primary that included an orthopedic surgeon, a clinical physiologist and political event organizer whose wide-ranging resume included stints as an autoworker, model and real estate agent.

The first-term treasurer was heavily favored to win.

He has already raised $4 million in his bid to unseat Democratic incumbent Sherrod Brown in the fall. Brown is a former congressman and Ohio secretary of state with a progressive following around the state.

Ohio Democrats have lobbed accusations at Mandel all year, including that he has neglected his treasurer duties for his Senate campaign.
