Reeder registered with Buchanan County Clerk Mary Baack-Garvey the day after the District's Jan. 17 deadline.
By registering as a write-in, Reeder did not have to obtain the 750 signatures required to be on the ballot.
Baack-Garvey said running as a write-in is risky. "You run the risk of people remembering your name, and remembering to fill in the oval," Baack-Garvey said.
Those on the ballot include: Martin Rucker, Lori Prussman, Dennis Snethen, Ham Henderson, Chris Danford, and Walt Hanabury.
The election takes place on April 3.
