In 2010 Mäenpää joined the Finnish Freedom Party (later known as the Blue and White Front) and the SKS became inactive. After the Blue and White Front failed in parliamentary elections, Mäenpää became the chairperson of the political association Suomidemokraatit that tried to get registered as an official party but failed.[4]
In 2017 the Turku court of appeals sentenced Mäenpää to seven months suspended imprisonment for forgery. This pertained to falsified electoral documents. The original sentence of the district court for Finland Proper was five months suspended.
