Call for Nominations: Best Campaign Web Site

At the Tom Sawyer MeetTheBloggers event last Saturday, Sawyer said that he had no campaign web site because he didn't want to do something unless he did it well (or words to that effect). He expressed disdain for webs sites that merely mimic a candidate's resume, and are not kept current. He said that he would get around to putting up a web site when he found the help and material to put together a good one.

I asked if he'd be interested in hearing from the blogging community about what's out there as fas as examples of quality campaign sites, and he seemed genuinely interested. So, let's hear it! What are some really excellent campaign sites? What do you like about them? Why do they matter?
