You hit the nail on the head. Greer will have a waiting line of deans from the major universities eager to make him commencement speaker and give him an honorary doctorate. (Michael will probably have to make do with the stipends afforded somewhat less distinguished guests. He's just too creepy for commencement ceremonies.)
You are very mistaken. Michael Schiavo will be the darling of the pro-death, Bush and DeLay-bashing left, and get $50,000 per speaking engagement. Given a modest 50 appearances a year (Ann Coulter does 60-80 annually), that would yield him $2,500,000. And that is without the almost certain $Million book deal and movie rights (Hollywood only wants his side of the story).
All of this cash is denied to him so long as Terri has life in her body.
