I think it's ignorance. We've seen the efforts to combat apathy, especially during the last political season and the subsequent year: rage, passion, and plenty of ignorance. "News" now consists of some talking heads yelling at each other, other talking heads desperately trying to label this group or that phrase or that other imagery as evil incarnate, interspersed with footage of extremists in the street screaming and breaking things. I think you'd be hard-pressed to find somebody apathetic about the state of the country right now, outside of those who are totally ignorant about it. And just because some people aren't vocal doesn't mean they aren't simmering about something. Educating a populace strikes me as far harder than getting them all worked up, doubly so after they've been all worked up.
