Starting today we're kicking off our weekly round-up of the 2008 campaign. Mainly we'll focus on the presidential race, as we do in today's kick-off episode, but not exclusively. We'll dig into the House and Senate contests and various down-ticket battles. We do a lot of digging into various aspects of the campaign. And in these episodes I'll try to distill it down to the key development and trends. We want your feedback. So let us know what you think, both of the show, but also our analysis. We'll include your responses and questions in future episodes.
