The New York Times wrote an interesting article about the DoubleClick Google deal which suggests the deal will get approved.
The article discussing a possible conflict of interest with the FTC Chairperson Deborah Platt Majoras stated that even if she removed herself the vote would be 2-2. It takes a majority to stop a sale.
Majoras' husband works for Jones Day who has been retained to represent Google in the matter. Interestingly another member of the panel, William E. Kovacic, is married to a partner at Jones Day, though no mention of a possible conflict there was mentioned.
