So you vote because you think voting gives you the right to complain?
I vote for who I hope will do the best job and if they don't then when they come up for reelection I would hope I could vote them out. If one never votes, one doesn't have the right to complain since they could have voted to make a change possibly. If one never votes they have no right to complain about who is in office as they could have voted to get someone in there to make changes.
