COLUMBUS — Ohio's Republican state treasurer Josh Mandel says he'll again challenge Democratic U.S. Sen. Sherrod Brown.
Mandel on Wednesday announced his campaign for the seat in 2018 that could set up a rematch of the 2012 Senate race in Ohio.
He lost to Brown by 6 percentage points the first time around in what was one of the country's most expensive and closely watched races.
Mandel, though, could face a primary race first in 2018.
He says he wants to continue the national movement underway to shake up Washington and empower the people.
Brown was among those mentioned as a possible running mate for Democratic presidential nominee Hillary Clinton this past fall.
The second-term senator also has served in the U.S. House and is a former Ohio secretary of state.
