Right Wing News lists Henry Hanks’ Crooow Blog as an up and coming weblog. As far as I’m concerned, though, there’s no up and coming about it — the blog is definitely already there.
I’m not usually a big fan of weblogs that are largely just links, but Hanks really excels at the form, in part because he seems to have a photographic memory of political events. If you want to see (largely left/liberal) politicians and commentators skewered by their own contradictions and hypocrisy, nobody else does it better.
