The Associated Press has this story, saying the Minnesota Secretary of State has formally notified the Independence Party that it has lost its qualified status, something it has enjoyed for twenty years. The party needed to poll 5% for one of the statewide offices. The party was very unlucky, polling only 4.9% for Secretary of State. Its other statewide results were: Governor-Lieutenant Governor 2.9%; U.S. Senator 2.4%; Auditor 4.0%; Attorney General 2.3%.
The party is free to ask the legislature to ease the 5% vote test. The median vote test in the 50 states is 2%.
