Senator Mike DeWine says Friday that he will run for Senate again in 2006.
The announcement ends speculation that DeWine would run for Governor of Ohio. Gov. Bob Taft must leave office in 2006 because of term limits.
DeWine has eliminated himself from an already crowded field of Republicans vying to represent the G-O-P in the governor's race.
Those expected to seek the post include Auditor Jim Petro, Secretary of State Kenneth Blackwell and Attorney General Betty Montgomery.
The 55-year-old DeWine was elected to the Senate in 1994 after serving four years as lieutenant governor under Republican Governor George Voinovich. He served in the U-S House from 1982 to 1990.
