confused again.

The two cases are not comparable.
Tiger Woods sponsors pay him to win golf tournaments. He does that very well when he can play. His wife's threat to drive his balls her way may yet get him abandoned but it has little bearing on his endorsements of golf equipment. It might enhance the relationship with Gatorade. “This is textbook in P.R. circles in terms of addressing an issue and bridging to a vision of moving forward,” Perlut wrote. “And that should suffice in terms of helping him manage his personal brand, which is worth more than $100 million annually.”
Eliot Spitzer has left public life. His proper response was Wellingtons: "Publish and be damned". The problem he faced was a perceived blackmail vulnerability. The republican party was hunting for him. His State Police guards sold him. I believe that he thought he could not function in such a hostile environment.
So, yes, golf is why tiger is so special. That and he is very pretty.
