Levi Johnston, the father of former Alaska Governor Sarah Palin's grandson, filed papers to run for office in his hometown of Wasilla, Alaska, next year.
Mr Johnston filed his letter of intent with the Alaska Public Offices Commission, a first step needed to begin campaigning.
The letter does not specify an office though Mr Johnston's manager, Tank Jones, said Johnston is interested in a run for mayor or city council.
Wasilla is where Mrs Palin got her political start, first as a council member and then as mayor.
Earlier this month, Mr Jones confirmed that Mr Johnston planned to run for office as part of a reality TV show.
Mr Johnston and Mrs Palin's daughter Bristol were thrust into the national spotlight in 2008, when Mrs Palin was making her vice-presidential run and the two were unwed expectant teens.
Mr Johnston (20) has had a prickly relationship with the Palin family since the birth of son Tripp and has sought to capitalise on his fame, posing for Playgirl and hitting the Hollywood circuit.
He and Bristol Palin recently broke off a short-lived engagement.
