Go to Ontheissues.com and see. It says he supports allowing physician assisted death under certain circumstances.
"I remember a case of a prominent individual who had been in an automobile accident and was rendered a C-1 quadriplegic, which means not only was he paralyzed from the neck down, but he could not breathe without assistance. We could have made the decision to keep him alive at all costs, but through a unique system of communication that we were able to work out with him, he indicated that he wanted to die. After much debate, we yielded to his wishes and withdrew ventilator support. In the long run, I think our course of action was both compassionate and pragmatic. If we integrate compassion and logic into our decision-making processes, I am convinced that we will deal with newly emerging ethical dilemmas appropriately."
Interesting. I had never heard that before.
