I'm not one to sign on to conspiracy theories of any kind, but when I was perusing the county by county results in Michigan I noted something interesting. Uncommitted got second place or better in all but four counties. In four counties uncommitted got exactly 0 votes.
If anyone has any information on why Dickinson, Houghton, Otsego and Wexford counties reported 0 votes for uncommitted I would be very interested.
Update: According to smitha007:
There was some kind of major computer programming error in 20 counties that registered uncomitted votes wrong, or something like that.
