What do the presidential candidates think about science and technology?

Three of the four major candidates for U.S. president have responded to “America’s Top 20 Presidential Science, Engineering, Technology, Health and Environmental Questions.” The nonprofit advocacy group ScienceDebate.org, who has posed questions and called for a scientific debate in each of the past three presidential elections, has posted their responses online. Hillary Clinton, Donald Trump and Jill Stein had all responded, with no responses yet from Gary Johnson. Overall, the answers seem to track ideological differences — Trump emphasizes market solutions to questions of science and technology, while Clinton emphasizes the role of the federal government in investing in scientific development and technology.
