This auction is allegedly ending early next week, so Bloomberg's late entry is presumably some sort of tactical move. Sez Keith Kelly:
Mayor Mike's company is now seen as the frontrunner, replacing Lazard boss Bruce Wasserstein, owner of New York Magazine and The Deal.
Jon Fine says that Bloomberg passed on BW already once before jumping back in now. There are at least four bidders in the hunt now. And, don't forget: Bloomberg is also a "potential candidate" to buy the Down Jones Indexes, when News Corp decides to sell them off. They're throwing money around like...frisbees!
