I'm not sure how power was shared between the Koch brothers, but who fills in this power vacuum of a person who probably had more influence over the US than any president? I'm sure there is a succession plan, and I'm willing to bet they can be even more successful in the Koch agenda.
It's a bit scary to see that a person who has all the best doctors and researchers available still dies at 79. Probably he didn't do everything to extend his life though.
