Why wait for it to be reported when you can go straight to the source? The Michigan legislature's web page now shows that SB 624 (the bill to move the state's 2008 presidential primary to January 15) was discharged from the House Ethics and Elections Committee today and was subsequently passed by a vote of 67 - 34 on the floor. The bill then went to the Senate where it passed the House alterations by a vote of 36- 0 with two either excused or abstaining members. Now the plan heads to Gov. Jennifer Granholm's desk where it is expected to be signed.
Your move Iowa and New Hampshire.
UPDATE: Ah, here's an AP account of what happened.
UPDATE II: And here is the story from CQ.
