There was one serious push for the Upper Peninsula becoming the state of Superior in the Michigan Legislature The push was made by Dominic J Jacobetti Sr was was probably the most infamous Michigan politician ever he served  years in the Michigan House of Representatives and died before term limits could move him out Jacobetti pushed for UP statehood in the legislature although polls conducted in Marquette and Ironwood suggested that Upper Peninsula residents did not want to become their own state I did a fairly large research project on Jacobetti and a good portion of it was dedicated to his pushing the UP as the st state I can add a bit about this later from my research paper which is well documented and backed by sources from the Northern Michigan UniversityCentral Upper Peninsula Archives which contains a wealth of material about the subject  An NMU PoliSci student
