In western PA where I'm originally from, voting against one's own economic interest is the standard. In fact, this is the kind of thing Obama was talking about with his "religion and guns" assertion. It amazes me how many are willing to vote against their own interest in the name of one or two issues (i.e. abortion, gun control, the race of the candidate). In many cases, the vote is borne out of a frustration with their own position and looking for someone or something to blame. Unfortunately, they often point to the wrong thing.
