Let me address one question being lobbed at me. Is raising questions about the Palin pregnancy a smear campaign? Here's why it's not. The circumstantial evidence for weirdness around this pregnancy is so great that legitimate questions arise - questions anyone with common sense would ask. The answers to those questions can easily be provided. This is an easier call than the "cross in the dirt" story, which will never be resolved one way or another. The McCain-Palin campaign can resolve this now with medical records, as are mandated for presidential candidates anyway.
The job of a press is to ask questions which have a basis in fact. Read for yourself the full chronology here. See whether you are certain there are no legitimate questions worth asking. I have claimed nothing. I am asking the McCain campaign to resolve a factual question which they must already have covered in the vetting process. After all, this baby was a centerpiece of the public case for Palin made by the Republicans. They made it an issue - and therefore it is legitimate to ask questions about it. That's all.
