<p>I agree with Michael's general layout plan (Issue, Viewpoint, etc.). The one thing I would add would be pages for candidates that included (among other things) evaluations of their campaign material. For example, on the page for Candidate A you would find transcripts of his/her speeches and advertisments. If in a speech they said "GDP has increased X percent while I've been in office" you could click on the phrase and find the source of the statistic and a discussion of alternative statistics and their accuracy. The wiki format would be good for this because everybody can add a bit about their personal favorite economic indicator. Hopefully the page would allow readers to assess the validity of the candidate's statement on their own rather than being told it was right or wrong.

<p>For the debate section, I would like to see something like Micheal's limited-response Lincoln-Douglas thing combined with George Murray's voting scheme so you would see the most insightful and polished debates first.
