So here's something new. Inspired by the likes of the Cook Political Report and CQ Politics, I've cooked up this chart of 2008's competitive House races, sorted by their likeliness to be retained or lost by the incumbent party.
The standard caveats apply here: the ratings shown are only indicative of the current state of the races. As the campaigns become more engaged and more information becomes known, many of these seats will shift position on the chart -- some, perhaps, dropping off altogether. That said, there will be opportunities for other races to be added if circumstances call for it.
Got a beef with our take? Want to post your own ratings? Stick 'em in the comments.
