In a video statement, Ohio Secretary of State Jennifer Brunner (D) today announced that she will run for Sen. George Voinovich's (R) vacant Senate seat in 2010.
As it stands now, Brunner would compete in a Democratic primary against Lt. Gov. Lee Fisher (D), who also has said he's running for the seat.
Former Ohio Rep. Rob Portman (R) -- who served as George W. Bush's budget director -- is the sole Republican so far vying for the seat.
