TheStreet's Jim Cramer says that Rupert Murdoch is building up cash by selling entities in Europe for a total of $9 billion. Cramer says that Murdoch will absolutely raise his bid for Time Warner but Cramer doesn't think Murdoch can go much higher than $90 billion because beyond that, "it's almost as if Time Warner is buying him." Cramer tells investors to stay the course and stick with Time Warner because either Bewkes will make investors money long term, or Murdoch will make them money in the short term. Cramer prefers the long term during which Bewkes could take the stock up to $120. Either way, Cramer tells investors not to sell Time Warner.
