I've voted at the elections which deserve my vote and I have elected not to vote at some elections because the options all suck and none of the above was worthy of my vote. I still felt I had the right to complain because I knew full well what I did and why.
Yogi; the difference between not voting and voting "none of the above" is that you'd quickly find out who didn't vote out of laziness and who didn't vote because there was nothing worthy of a vote.
we have elections every other year, local and national every other time. In the local election we have the "none of the above" alternative, but not in the national elections. Sad really. I don't know why (or I do not want to be right, I'm not sure which)
