What prognostication? He basically just said “If you invade Persia, a great empire will be destroyed.” If Coakley wins, he can say “Yep, I called it—more Democrats showed up.” If Brown wins, he can say “Yep, I called it—Coakley was cooked unless more Democrats showed up.”
So, you agree with him basically saying that it can go one way, or the other, when other up-to-the-minute polls show that the Democrat in this race is cooked?
Do you really think that it's responsible for a recognized national pollster to do that? Maybe you don't care, but I can guarantee you that people who pay good money for his polling will look at what he's said quite a bit differently.
