Did French Corporate Lobbyists Steer McCain to Cancel $100B Boeing tanker Contract?

Its well known that Presidential Candidate John McCain was probably singlehandedly responsible for getting a USAF $100 Billion Tanker contract to Boeing canceled.  The contract was subsequently awarded to Airbus instead. 

But its now coming to light that McCain has 7 corporate Lobbyists representing Airbus on his Campaign Staff.  Not only does McCain have French Corporate Lobbyists on his campaign staff, but they are also significant financial contributors to his campaign.
