Finally, just what I've been looking for: the Political Base wiki. Its aim is to collect all sorts of unbiased political information which anyone can add to. However, unlike Wikipedia, all submitted information must first go through a staff editor.
I've only taken a brief look so far, but I really like the fantastic chart for comparing the candidates. It makes it really easy to find out who supports which issues!
I have often felt I do not keep up with politics thoroughly enough to be a competent, well-informed voter. This web site looks like it will be quite helpful in that area.
