> Which isn't surprising I guess, as people who don't vote are probably happy with the status quo. If they weren't, they would vote.
That may be true of most, but it certainly isn't true of everyone. For example, I don't vote, not because I don't care about what those in power do, but because I dispute the legitimacy of the power itself. Voting would be an expression of support for the concept that *someone* should hold the office, and its power, regardless of who wins. There is no way to vote for eliminating the office, or even simply leaving it vacant, so I abstain in protest to avoid legitimizing it.
A candidate receiving X% of the vote means that approximately X% of those who voted thought that candidate was preferable to the other candidates listed on the ballot. That's all. It doesn't mean X% of the voters support most or (especially) all of that candidate's policies, or that X% of the population at large would make the same choice.
