Democracy couldn't exist if there was a mechanism to say certain votes are irrational and shouldn't be counted. It's not a perfect system but it's the best yet.
I'm not saying there are votes that shouldn't be counted, but I do think the electorate is generally so disengaged and uninformed that it makes a farce out of anything. It's like a blind person attempting to drive a car. It's still better than non-democratic alternatives, but I think that has more to do with how all of the arcane pieces that make up the system happen to divvy up power enough to prevent it from becoming too centralized, and there's sort of a looming threat that the people could turn against you. It isn't because the core concept of the people actually controlling their own government holds much weight, at least not in how most people seem to conceptualize it.
Really I'd like for this not to be the case, but at the moment it seems like that isn't likely to happen anytime before I'm dead.
