I literally didn't make up my mind who to vote for until the moment I cast my vote. I felt Obama was blocked by Republican party in Congress. I'm still not convinced he and his advisers have the negotiating/political skills to achieve what has to be done. I felt that Romney was out of touch and I knew he wasn't liked by most European governments.
In the end it came down to who I felt showed a stronger commitment to Judeo-Christian teachings about treating your fellow man. And that was still a tough one because of Obama's abortion stance (Not going to get into that
because I'm still trying to strengthen my thoughts on abortion).
In the end I voted for Obama. As I say at each President's inauguration, "He won't be the best President we've ever had, but he won't be the worst either. He's what we've got."
