The code-head thing I hinted about? Well, for one thing, the site is now being served as XHTML 1.0 Transitional (though there are some minor validation weirdnesses). For another, if you view source on the main site pages (i.e. the pages that aren’t part of the Blog Formerly Known As Kicking Ass), you see mt-* URLs, including mt-search.cgi. Word has it that the whole DNC website has been ported to a customized, mostly static version of Movable Type.
I could be wrong, but I think this is the first time a blogging platform has taken over an entire web presence for a major American political party. (For all I know, that sentence doesn’t need the qualifier “American,” but I don’t have enough information to go out on that limb.)
