These are election coverage tactics that peaked my interest. For good or bad they are listed in no particular order. If you know of others, please post them to the comments.
Candidate match game - USATODAY.com This is really well done.
2008 Election Collection Widget - Washingtonpost.com About, News, Campaign Events, Funds
This is a fun widget. Click on the more on Campaign Events and they use Google maps to show the location of the event. There is a lot of good information, but the numbers are hard to translate, because there are no side by side comparisons on specifics.
Election Guide 2008 - NYTimes.com Candidate finance (Flash), Schedules, Calendars, multimedia, quotes about issues
Overall this is a pretty nice package, but it has a little room for improvement. I feel like over all the site could be more visual. There are just a lot of database driven lists, but they aren't as informational as the Washingtonpost.com's lists.
ElectionVine - Newsvine.com This is a super cool toy. Newsvine created a voting widget that people can place on other sites. Then when people vote from other sites, the info is brought back into newsvine. Newsvine gives an overall picture of who is in the lead according to their poll, and then breaks it up by website. (See this in action on this blog. I have it in the right column.)
Campaign 2008 - CBSNews.com This is a good idea, but it is very flawed. A lot of the visuals are simple, which makes them easy to understand, but after you are done consuming it once, you are done forever.
The navigation is horrible. It took me a second to figure out how to get around, and some how I switch multimedia and found myself looking at the 110th congress and not the election. I had to retype the url to get back to the start.
AP Content
Campaign Finance I don't think anyone is doing anything that is this comprehensive. Too bad I had multiple errors that read "Error loading XML file." One of the errors appeared when I tried to load the map. The thumb of the map on elections page looked much like the NYTimes thumb.
Race '08 where the candidates stand Clean and start forward chart of where the candidates stand. Only problem - I can't figure out why it was made in Flash. Flash lessens accessibility. This could have easily been made with HTML and CSS.
The Truth-O-Meter - St. Pete Times "A scorecard separating fact from fiction." This project looks at what candidates say in comparison to how true it is.

Candidates + issues matrix - MSNBC.com This combines both the candidates and the issues. You have the ability to agree or disagree with the candidate. It's a pretty neat project, because it combines more than one layer, but it is slightly confusing and takes forever to load.
This project needs a simplified overall summary of all users. If you click on the all users' ratings tab, you will see a sea of green and red. While you can zoom in to get specifics, I think the checker board is a little overwhelming.
