I take an in-between position on this.  On the one hand, I don't think an orgy of speculative posts full of arguments about whether she or her daughter "look" pregnant is either useful or right.  On the other hand, some people on this and other boards seem to be taking what I consider a self-righteous and politically mistaken view against even thinking about this.  I think it's a legitimate story.  Personally, I'm not sure how much it should matter, beyond a vague sense that if true, it seems freaky and puts focus on the scary world of the religious right.  I definitely think that it would matter to many voters, and would be a net negative for the GOP ticket.  Mattering to voters is my criterion for whether legitimate news sources should investigate a story.  And that's what I think they should do, right now and thoroughly.  I certainly hope and expect that the Enquirer is on it.  So don't bloviate about it, but push for it to be looked into and confirmed or not.  Here's my vote for at least TPM to get started.
