That's a bit of a straw man. Nobody says voting will get you the government you want. I can't get any of my liberal friends (core Hilary voters) to care about surveillance. To the extent they're nervous about surveillance as a general concept, they trust Obama has struck the balance necessitated by what he knows about threats to the country.
Not everyone should vote. If your views are substantially outside the mainstream there is no point in voting.
