Let's take a look at the ARDA numbers.
Episcopalian:
http://thearda.com/mapsReports/maps/ArdaMap.asp?Map1=290&map2=&alpha=Based on the distribution, appears pretty D. It's obvious how the ones in New York and New England voted, Pennsylvania's are all concentrated in metro Philly, Florida's are mostly concentrated in Democratic areas (aka not the panhandle), Virginia's in NoVA, Georgia's in inner metro Atlanta. California is more skewed SoCal, but I doubt there the ones voting Republican there. I suppose it's possible the more southern ones might be R-leaning, but not enough to cancel out the northeastern ones.
PCUSA:
http://thearda.com/mapsReports/maps/ArdaMap.asp?Map1=551&map2=&alpha=Largest state is Pennsylvania, and there I'd guess Obama since the largest concentration is Philly area...but there are a lot in those counties around Pittsburgh that swung heavily against him. Not many in the "T" though. North Carolina is second, and there I'd guess Romney, but less than whites in the state. Texas' are obviously Romney, and in Florida they probably skew rather old. Overall probably for Romney, but I doubt as much as rfayette is making it sound.
ELCA:
http://thearda.com/mapsReports/maps/ArdaMap.asp?Map1=317&map2=&alpha=I'm not giving an inch on this one being for Obama, and the data backs me up. Very low presence in the south. Top states are Minnesota, Pennsylvania (hmmm a bit out of place) and Wisconsin. Actually the Pennsylvania numbers appear to be mostly concentrated in conservative German areas (not surprising) so that might skew it a bit, but considering how R the
other Germans are in those areas I can't see them being that R. Also worth noting per the 2008 exit polls Obama won non-evangelical white Protestants in Minnesota, Wisconsin and Iowa with around 57-60%, and while I don't have exit polls in 2012 the swing wasn't large enough to make that not the case. So you have the largest non-Pennsylvania states voting around 55% Obama...even if the Pennsylvania ones are as R as those counties R it's not enough to cancel it out.
