>> INSIDER WIRE —More rumors have hit that Anna Wintour is looking for a place in the Obama administration — possibly as ambassador to Britain — but a rep denies them, and we can likely chalk it up to the fact that she has contract negotiations coming up.  But it sounds like the Anna situation isn't the only thing Si Newhouse is about to have on his plate: New York's Monday cover story — online Sunday night at 10 pm — is titled "Si Newhouse's Dream Factory" and the teaser reads: "Conde Nast's own stars compare their glossy empire to the MGM of Old Hollywood, but no one would wish it the same fate. What happens to a magazine empire built on glossy fantasies when harsher realities intrude?" [Page Six, FWD]
