Levi Johnston, the former fiance of Sarah Palin's teenage daughter Bristol, has filed official papers saying he intends to run for political office in Palin's Wasilla, Alaska hometown.
Johnston, 20, has been embroiled in a nasty feud with the former Republican vice-presidential candidate since fathering Bristol's baby out of wedlock two years ago.
He filed a "letter of intent" with Alaska authorities on Friday, stating that he plans to run for elected office in Wasilla in 2011 elections, according to documents obtained by celebrity web site TMZ.com.
Sarah Palin, the polarizing conservative politician widely thought to be planning a U.S. president in 2012, was once mayor of the small Alaska town.
Johnston signed up earlier this month to shoot a TV reality show that will chronicle his attempts to follow in Sarah Palin's footsteps as Wasilla mayor, and attempting to launch a career in Hollywood.
Johnston's filing allows him to officially start his campaign and accept campaign donations.
Johnston and Bristol Palin broke off their engagement for a second time three weeks ago after announcing in a celebrity magazine that they planned to marry and raise their young son together.
In the past year, Johnston has posed nude for Playgirl, and publicly criticized Sarah Palin and other members of the Palin family before apologizing.
