FRANKFORT — Republican Bill Johnson, who enjoyed support from the Tea Party movement in his aborted run for the U.S. Senate this year, has officially entered next year's race for secretary of state.

Johnson, 44, of Todd County paid his $500 filing fee Monday morning in the secretary of state's office. He is the first candidate to file in next year's races for state constitutional offices, which will include the race for governor.

Johnson said he is running for secretary of state because it fits with his desire to defend the Constitution.

The secretary of state oversees elections, corporate filings and official state records. The office is now held by Republican Trey Grayson, who cannot seek another four-year term.

Also, former Montgomery County Judge-Executive B.D. Wilson said he will file Tuesday as a Democratic candidate for state agriculture commissioner.

That position is now held by Republican Richie Farmer, who is running next year for lieutenant governor on a ticket with gubernatorial hopeful David Williams, president of the state Senate.
