The Minnesota Senate State and Local Government had been scheduled to hear testimony on SF 1827 on Tuesday, February 28. However, the hearing was cancelled at the last moment. In anticipation of the bill, though, a press conference organized by minor parties got some publicity. See this story.
The bill would have stiffened the definition of a qualified party from a group that got 5% at either of the last two elections, to 10%.
UPDATE: the news story has a link to a video of the press conference, which is worth watching. It lasts about 35 minutes.
