The Washington Post today launches a new daily guide to the '06 elections, "Bellwethers: Key Issues in the Battle for Congress." The feature focuses on how voting may be affected by eight major "issues," including: Iraq; immigration; President Bush; corruption; "pocketbook" concerns; GOP chances in the northeast; Democratic chances in the "upper south"; and ballot measures. The feature includes dozens of cross-links to useful data, including candidate bios, district and state demographic profiles, opinion polls, financial information and voting records -- much of it nicely illustrated with clickable maps and jazzy graphics. WaPo says 'Bellwethers' will be an "organic" feature, which presumably means it will be updated and expanded with new developments. 'Bellwethers' offers substantially more easily-accessible content than the New York Times 2006 Election Guide and promises to be the best election tracking gateway offered by a daily newspaper
