Uncertainty and Politics

I am going to discuss this in a very mediocre format, so bear with me. Americans dwell within a democratic society where our votes can largely shape the structure which in we live. Of course, we are not used to dealing with issues from day to day, and probably only use our democratic powers when we vote once every four years for our president. We probably rarely, if ever, communicate with our elected officials. However, when it comes to voting for our President and issues that spike our interest more than usual (for instance, the recent developments regarding same sex marriage), how do we decide where to vote when we are not happy with either sides of an issue, or are not certain where to vote? As for myself, I doubt pretty much everything I get the chance to think about. That will probably include this post when I am done writing it. So how do I (when I am pompous enough to believe, and probably wrongly so, that I think on certain issues more than the average Joe or Jane that votes) vote on issues that I am uncertain about? Should I let many others who do not make thoughtful decisions choose the outcome? Is not voting really accurate of my view if I care very much about the issue? I don't believe we can trust on what "we feel good about." There are many decisions that I think may have been the right decision but I felt or still feel insecurity about. Marriage was one of them, but I do not think that was the wrong decision. I think we often have competing claims made upon us, and choosing one is to the exclusion of the other, and so we are bound to feel some insecurity for excluding the other claim which had good to it. So what to do? Do we pick to stay the course? In other words, when we are not certain about a topic, ought we stick with the original position if the alternative is a radical departure? Of course with non-radical departures, we would be more willing to give and take. Hmm... thoughts are appreciated. I am sure this is a difficult issue regardless of when it takes place, and there is no perfect way to follow it out.
