My experience is that people do not remove anything but loose papers.
I would only leave comments if they are funny.
Besides, if it makes me feel good, that is the goal.
The less of my money that goes to a dirtbag like Cheney, the better. May the old fart choke on his pilfered millions.
It will be a long time before his book gets to my library, anyway. Odds are I will see all that is of any interest in the newspaper or in some news magazine. Books by politicians are uniformly boring and far too long, in my experience.
