Imagine a scenario where one the local officials you voted for is caught misusing city funds. I'd imagine you want to know this come election time. How else does democracy work, if voters don't know what happened?
I'm not saying that what currently passes for news is a good solution, but I feel like a lot of people sort of throw the baby with the bathwater and justify completely detaching themselves from what's happening because news are heavily flawed. They are, and I don't blame anyone person from taking a break, but it doesn't scale. If a large percentage of the population does it it causes problems.
