Here is an interesting idea: holding a Presidential debate exclusively on science. Having some understanding of scientific issues is certainly essential to effective policy-making in many areas, especially medicine and the environment. A televised debate could allow voters to gain an appreciation for how strong each candidate’s understanding of science really is, when they do not have advisors to fall back upon.
That said, I doubt candidates would be keen to hold such a debate. For one thing, most of them would probably embarass themselves. For another, science has become such an acutely politicized field that such a debate may just reflect existing ideological stances.
This is being discussed on Slashdot.
