Presidents (and less so, veeps) have to keep pretty punishing schedules. Cheney might not be up to that any more, though as long as he can still think and talk he would be very valuable in conservative think tanks.
I’ve actually met him. He is incredible. Brilliant. Polite. Well mannered. One heck of a good shot and funny like you wouldn’t believe. I wish America respected its elders. I remember thinking during the swearing in (that Obama botched!) when Aretha Franklin started singing that it would have been nice to have HER as president because of her wisdom and grace. She may harbor some of the same bitterness, but she is first and foremost a lady of grace and charm. Plus, she earned it as a REAL African American. Obama is an impostor and makes Blacks look bad in general...
