I was up in Flint and a couple of the suburbs yesterday. I did not see one Obama sign there. I was not in the slums, but that whole city is Democrat. I did not see one sign.
Michigan Democrats (or, really, those who think the Democrats will "save" them) may not vote for McCain/Palin, but I don't think they are thrilled to get out and vote for the 'Bid D' as they were in the past.
Pray for rain/snow in Michigan on Election Day!
