I don't disagree about the principle and am a pretty keen voter, but if I look back over the years, when I had three small kids and a crazy work life, I probably missed a ballot initiative or a local election or two. Even without the snow and the thugs, these state level elections can be tricky when they're out of the usual voting cycle. They don't get the same level of publicity as by-elections here.
That said, the number of people who opt out is depressing, in part, because a lot of them see the whole system as too broken to bother. My young adult kids have lots of friends who see the two parties as indistinguishable in that they're mostly populated by old men with not much understanding of the world young people are facing. They see them all taking donations from AIPAC and some vote third party and some walk away in disgust.
The Democrats have got to find a way to make themselves seem relevant and at the moment they're failing.
