There aren't any, so you're not going to see any, not that anybody in his or her right mind would want to. If there were, perhaps I would be invited to yet another panel on blogging that does not include any political bloggers, but that does include faux journalist and even faux-er blogger Jeff Gannon/Guckert.
I do not believe this is an oversight or dumb-assed misassessment of who is writing blogs. More likely, it is journalists who organize these things preferring to protect their shrinking franchise on acceptable opinion-mongering. They do this by organizing a geek show and calling it a panel on blogging. Serious bloggers need not apply.
One doesn't have to dislike Wonkette and her site to recognize that she isn't really an appropriate representative of political bloggers or lefty political bloggers. Full disclosure -- I've been on a panel with Wonkette. I'll also be on one this weekend with Michael Wolff. Most importantly, I actually don't really like doing these things so this post should not be put in the green-eyed monster category.
