P.S MI will be the shocker of the night on Tuesday.
Voting history is taken into account for polling. There was no real primary in 2008 (Obama withdrew his name in protest of the delegates being revoked) and Obama was unopposed in the state in 2012--there was no precedent for them to really work with (and MI's primary polls have been off for awhile, as bad as Nevada's GE ones.)
