My two cents: Had it not been for a huge turnout and vote for Barack Obama, who won 60% of the California vote, Proposition 8 would most likely have lost. The huge voter turnout of minorities for Barack undoubtedly included their strongly Biblical view of marriage. That, combined with a larger than usual evangelical and conservative vote [those bitter, gun-toting religious wackoes], helped it pass with a 4 point margin.
The map is self-explanatory and shows a simplified demographic of counties that voted for and against the proposition, along with percentage strengths.
So, thanks again to our new President [and, of course to the God of Presidents] and his army of volunteers who registered new voters in California!
Unfortunately, this spiritual battle is far from over as all such warfare is destined to be in this world.
