I don't think this should be allowed

No, no, not Mary Cheney's pregnancy--that's great. Good for her and her partner.

No, what shouldn't be allowed is this: "The vice president's office declined to elaborate on the circumstances of Mary Cheney's pregnancy." I don't think the vice president's office should be allowed to decline to elaborate, and furthermore I don't think the vice president should be allowed to use a spokesperson.

I would like to hear the vice president himself explain why mentioning that his daughter is a lesbian is personal, political attack. Buncha lousy hypocrites.
