The places I'm thinking of are The Huffington Post, Project for the Old American Century, The Smirking Chimp. I get a fairly constant anti-Hillary buzz from those sites, even though I like all of them and visit them frequently, despite their sinful tendencies. I also like Buzzflash, which whomps Hillary fairly frequently.
A site with a more balanced view of Hillary Clinton (in my opinion) is ThinkProgress.
Er, uh...links:
