There are lots of reasons people don't vote (including my own, which I wrote about in this comics post). But one reason that seems to keep coming up is that people don't feel they're informed enough. For example, a person might not vote for their city councillor because they don't feel they know enough about the candidates and wouldn't want to influence the outcome of the election with an uninformed contribution. (Well-intentioned, I guess, but sometimes it's still a good idea just to exercise your right to vote - you know, let the government know that we care about democracy!)
And that's an awkward spot to be in. How can you ask without feeling silly? Shouldn't you just magically know this stuff?
Here is a little comic strip for folks who wish they had a better handle on the most basic stuff. Even with three more days until the election, it's never too late to learn!
If you want to know more about what city councillors do, you can read this very straightforward (and rather fun to read) post about their job description, on the VoteKit site.
