Presidents have had science advisers in one form or another since Franklin D. Roosevelt. The position gained new importance in 1976 when Congress established the White House Office of Science and Technology Policy (OSTP). The OSTP has a mandate to advise the President and others in the Executive Office of the President on the effects of science and technology on domestic and international affairs.
According to its website, the OSTP and science adviser, who until recently held the title “assistant to the president”, has had some success in the past in pushing programs such as the Human Genome Project and getting support for doubling the budget of the National Institutes of Health.
As previous science advisers told Physics Today when current science adviser John Marburger was nominated in 2001, access to the president is critical. Through direct contact, the science adviser not only can discuss policy with the president, but he gains status as a true “insider,” an invaluable asset when dealing with the federal bureaucracy.
In that regard, despite the experience and long list of eminent scientists providing advice to the Clinton, Obama, Romney, and McCain candidacies, only John Edwards and Hillary Clinton have explicitly stated that they will return the science adviser position to its previous rank of “assistant to the president.”
