Dowd has a history of writing some pretty nutty things. I remember about 6 monthes ago, she had written something about lesbians in a Washington D.C. high school. She pretty much wrote about how great it was to have lesbian teenagers, then she bashed bush. I am not quite sure how someone can write about lesbian teenagers and bash Bush, but she managed to do it. Also, Dowd does not really like men that much and her writing reflects it. If you really want to read some weird paranoid stuff, check out her columns in the NYT. It is kind of funny, but mostly sad.
Some of Dowd's work is indecipherable, as if she's on 15 minutes deadline and starts hammering together completely disconnected, random thoughts.
But you're right, she's always thinking about GWB, even after a tough session of exerting her noodle on the topic of high school lesbians.
