I tend to not bother voting for issues that don't concern me. And frankly, the vast majority of issues that people get all excited about don't bother me one way or another.
I'm happy to pay a little more or a little less tax on various things, see schools built in one area and prisons not built in another. Go nuts with it all, and if it really effects your happiness I'm fine with letting you make little changes to the world around me.
Until you come up with something I find important, I'd prefer not to concern myself with it.
