I wonder which is Icahn's real strategy. He can't be so stupid to believe that CI shareholders which are 90% of ESRX shareholders will vote down the deal.

These funds already own both companies. If they merged, they would still own them - and get a nice chunk of cash in addition. Why would they vote to own them separately and forego the cash?
