RUSH KNOWS ALL ABOUT HOUSEKEEPERS…. As controversies go, Supreme Court nominee Sonia Sotomayor’s membership in a New York-based professional women’s organization seems like pretty weak tea. The judge is apparently one of about 115 women in the group, known as Belizean Grove, which describes itself as helping “women pursue more significant dreams, ambitions, purposes, transcendence, and spiritual fulfillment.”

The group reportedly was created as a counterpart to the all-male social club the Bohemian Grove, which also is known for its influential members and networking opportunities.

Sotomayor told senators this week the club does not “invidiously discriminate on the basis of sex,” and it’s unlikely anything will come of this.

Rush Limbaugh, though, the classy guy that he is, had his own a unique take on this today.

“Today, my friends, we turn our attention to the latest revelation from Judge Sonia Sotomayor. It appears that Ms. Sotomayor, the model of diversity and inclusion, has some explaining to do regarding her membership in a club. Not just any club — a club whose members are all female….

“Safe to say, any conservative in this situation would find their nomination dead in the water. Clubbed — like a baby seal. No question about it. I think I’m going to send Sotomayor, and her club, a bunch of vacuum cleaners to help them clean up after their meetings.”

Obviously, this kind of ugly comparison about professional women is obnoxious and insulting. It’s par for the course for Limbaugh, but that doesn’t make it any less offensive.

That said, given his notorious background, I have a follow-up question: does Limbaugh really want to start making housekeeper comparisons?
