Cain's 65. Everyone knows he couldn't become a governor for 4 or 8 years, then run for president. BTW, GA just elected a new governor. The next time Cain could run for governor of GA would be 2014. If he served two terms, he'd be ready to run for President under their plan in the 2024 presidental election--when he's 78.
It's a red herring--code for "go home and shut up."
I Cain's ideas are solid, they're solid whether he's held political office or not.
