Ramsey was expected to file papers by the day's end to run as a Republican in the August primary of Michigan's 105th House legislative district, the Petoskey News-Review reported.
JonBenet was found dead in the basement of the family's Boulder, Colo., home in December 1996. Her murder has never be solved.
The northern Michigan district Ramsey was reportedly interested in includes all or parts of Antrim, Charlevoix, Otsego and Cheboygan counties.
Ramsey would become part of an already crowded field in the GOP primary, which already includes Craig Ryan of Gaylord, Kevin Elsenheimer, a municipal attorney from Bellaire; Bonnie Nothoff, a dental hygienist from Kewadin; and Jeff Garfield, an Otsego County commissioner.
Incumbent Ken Bradstreet cannot run because of term limits.
