Well, even "Mainline Protestants" are no monolithic voting block. I'm LCMS Lutheran and far more conservative than some ELCA "brothers". But much of this has to do with church hierarchy and not the flocks they oversee. I know a good number of ELCA Lutherans as conservative as I. They go to church for communion with God; not for political indoctrination. But I left the ELCA simply because I'm intolerant of such political incursion into my religious beliefs.

David Limbaugh, the smarter one in my opinion, speaks of many evangelical leaders worried that up to 40% will vote for Obama. If this plays out as Clinton-Dole, I see that as a real possibility.
What! You don’t go to church to get guideance on who to vote for? You go to worship and learn more about God and his son? Amazing.
