Boman was the Libertarian candidate for United States Senate in 2012. He placed third with 84,480 votes; the most votes earned by a third-party United States Senate candidate from Michigan since Libertarian Jon Coon ran for that office in 1994. He was also included in two statewide scientific polls in the post-primary season. The last time a minor party candidate was included in such polls was in 1994. Because of an initial attempt to run as a Republican, Boman was also included in pre-primary polls and placed third, in a field of eight declared Republican Primary candidates. In 2008 Boman was not included in the traditional PBS televised debate due to a lack of poll results, and Boman argued for inclusion in the debate based on a 7% showing in a Poll he had commissioned. Incumbent Senator Debbie Stabenow refused to participate in the forum, shortly after Boman's release and the event was never scheduled. Republican challenger, Pete Hoekstra also refused to debate him after the primary, but Green Party opponent Harley Mikkelson debated Boman on a few occasions.
