Michigan Political Parties: Progressive Party (1912)
A struggle between progressives and more conservative elements over the Republican nomination for president in 1912 led to the formation of the Progressive Party led by Theodore Roosevelt. Michigan governor Chase S. Osborn was an early supporter of Roosevelt. The Progressive Party in Michigan was active in the elections of 1912 and 1914, but had disappeared by 1916.
This party is documented in the papers of Chase S. Osborn and Henry R. Pattengill (the Progressive candidate for governor in 1914).
