I have Mormon neighbors that are voting for Obama. They are big, big libs. I was shocked.
Look, I don't agree with various groups on their religious beliefs but I'm more inclined to support people who are on the right. There's something about liberals that's just not right... It's like the difference between good and bad. Even within my own faith, I see the difference. It always amazes me when I can sit in church with a lib and we come out of service hearing two different sermons. How can anyone who goes to church believe in gay marriage, abortion, free contraception...etc?
Maybe your neighbors got to their personal limit on what it means to be a Liberal these days. That would be an interesting question, if you could ask it in the right way, i.e., so you would get an answer rather than a “harrumph”.
In answer to your last question - I have no clue whatsoever. Sometimes the best thing I can do is take a deep breath and pray for guidance.
