Commissioned by the Library of Congress, a terrific new site called PoliticalWeb.info that provides access to the largest and most comprehensive digital collection of resources ever published on the U.S. campaign and election process. See the press release about last week's launch of the site here.
Among the resources available are a chart indicating the availability of several dozen useful features for voters from 2004 Democratic Presidential Campaign Sites, ranging from accessibility to speeches, for the declared candidates (Kerry, Dean, Lieberman, Edwards, Gephardt, Sharpton and Kucinich).
Another resource is the impressive and very useful tracking tool, Election 2002 Web Archive, a database with a "selective collection of nearly 4,000 sites archived between July 1, 2002 and November 30, 2002," from "505 races for U.S. congressional and gubernatorial offices." Users may search this database by Office (Governor, House or Senate), Party, State, Candidate Name, or All Candidates.
