Neil DeGrasse Tyson is an astronomer that is approaching Carl Sagan status, at least in my mind. He is a great communicator. He is on a book tour and received the question about the Republican war on science. I always felt that it was a misdirection. While two big science areas of debate were politicized, were embryonic stem cells and the environment. However, as Dr. Tyson points out, budgets for science went up during the Bush years and down during the Clinton years. Also to point out that Dr. Tyson is a liberal, by his own admission.
Watch the clip from Fora.tv in fact if you have the time, watch the whole hour and change of his talk and the Q/A session after. Fascinating.
