My sympathies for his family.
I would also like to express the same sorrow toward him as he had toward the 10’s or 100’s of millions of people in the future who will suffer and die because his philosophy of greed and selfishness, wrapped in the lie of Libertarianism, prevented us from doing something about the civilization ending catastrophe of Global Warming, and for the millions today who suffer because he dedicated his life and fortune in preventing the government from helping those among us who need a helping hand.
UPDATE: Expressions of sorrow are coming from around the country.
The response on twitter is really FAR colder, but justified, than I expected.
