State Treasurer Josh Mandel and five other Republicans will face off in this year's Ohio GOP primary for U.S. Senate.
The state's top elections official on Thursday announced the list of Senate contenders who will appear on the March 6 primary ballots.
The winner of the 6-way Republican contest would likely face incumbent U.S. Sen. Sherrod Brown, a Democrat, in November in one of the nation's most closely watched Senate races.
Democrat Mark McGinnis is listed as a write-in candidate challenging Brown.
