HMm..
I still think that people who don't vote cannot complain, since they have not been bottered to take a stand for changes. At same time he have a point, if you vote on someone that does the changes you are also responsible for that. But at same time, many times you vote on someone, and their politics turn out to be something different than what they promissed. I think you still have the right to complain than, since it's not the politics you vote on.
But hell I know, time to get drunk!
