Wow. Andrew Sullivan's unhinged hatred for Sarah Palin continues unabated. Three weeks ago I wrote about his descent into the ugly world of tabloid journalism pushing rumors about Bristol Palin being the "real" mother of Sarah Palin's fifth child, Trig.

Yesterday we learned via Howard Kurtz that Sullivan is still fixated on pushing the rumor:

Last week, Sullivan, a British conservative who became disgusted with the Bush administration and is a passionate advocate for Barack Obama, sent an e-mail query to the McCain campaign:

"I'm very sorry to say, it's come to this: can you confirm on the record that Trig Palin is Sarah Palin's biological son? . . . Since this is a crazy idea, it should be easy for you or someone to let me know, the most popular one-man political blog site in the world, what the truth is."

This from a man who condemns McCain and Palin on a daily basis for being "despicable" and "dishonorable." Unreal.
