While it's true that the Marquette area is probably more liberal than the SSM/Mackinac part, neither can effectively be compared to the coal mining regions of Pennsylvania,
I don't really see why not; despite the differences (which are largely (but not entirely) due to the different ethnic composition of the two areas) they are *reasonably* similer; certainly *not* an exact match though.
Not at all. The PA coalfields are strongly Catholic for the most part; the religious patterns of Central Appalachia are unique in the U.S; religious, yes, Evangelical, yes, Church going... not usually. At least not to the same extent as in the rest of the U.S
Lot's of small Charismatic churches, chapels etc. as well.
