Grun, I used to have a similar point of view about voting. The thing is... no matter how up to date you may be on who is running and what they stand for it is all for naught if you don't vote.
My father-in-law made the point to me very directly one time. I had just entered a discussion with him and others in the family about the upcoming elections (this was in the late 60's if I recall) and after listening to what I had to say he asked me "Are you going to vote?" I said no and explained my reasons why and he said "If you are not going to put your money where your mouth is by voting then your opinion has no value at all." I thought he had a point and made it a point to vote from then on.
