Outside Dearborn that is not at **ALL** true.
Even in Dearborn, a significant percentage of the Arab population consists of Christians who fled Islamic persecution and have absolutely zero tolerance for Islam, knowing what it is from firsthand experience.
When I grew up in Grand Rapids, which has never had a Democratic Party majority on the Kent County Commission in the entire history of the state since the county was organized in the early 1800s, it was not uncommon to see bumper stickers saying “secede from Detroit.”
Michigan's blue collar Detroit suburbs were the center of the “Reagan Democrat” movement.
The state is winnable if a candidate has the same attributes that made Democrats vote for Reagan.
Whether Mitt Romney is that candidate is questionable, but given his personal ties to the state, he may have a better chance than one would expect.
I have a nephew in Grand Rapids, and he is strongly GOP. He is in the same strangle hold in Michigan than I have in Minnesota.
Rural areas of Minnesota are largely conservative. Our MN Sixth District goal is to sweep all the state legislative offices for the GOP - 100%. It is actually doable. Not all Minnesotans ot Michiganers are dimwitted Democrats!!!!!!
