Google News has a new section for the US elections. The elections page also includes a tabbed gadget that shows videos, news and blog posts related to your favorite candidates. While the gadget is customizable, the changes aren't persistent and don't propagate to the entire elections section.
Earlier this year, YouTube and CNN organized two debates with the presidential candidates and most of the questions were from YouTube users. Some of the candidates visited Google's headquarters and spoke with Googlers: from the eight videos, Ron Paul's conversation was the most popular.
Yahoo News has a nice dashboard with up-to-date information from polls, search queries and predictions. I wonder why Google doesn't link to Trends charts that compare the candidates.
