People dont vote because they dont feel like their views are properly represented. If each individual issue was open to referendum or voting, the only people who would take part in that specific vote are likely people who are well informed and passionate about the issue. I think this would end up being a far better system than having to vote based on nebulous campaign promises that are hardly ever fulfilled, or when they are, your issue is tacked on or bundled with a whole bunch of irrelevant and even harmful legislation.
