Science is slowly coming into focus in the US presidential campaign. Although neither Republican Donald Trump nor Democrat Hillary Clinton has emphasized core research issues, the candidates — and their parties — are beginning to flesh out their positions on climate change, education, biomedical research and other topics that involve the scientific community. Trump’s pick of Indiana Governor Mike Pence as his running mate on 15 July signalled a sharp turn towards the Republican party’s conservative base. Pence, a self-described Christian conservative, has questioned the existence of climate change, waffled on evolution and criticized President Barack Obama for supporting embryonic-stem-cell research. His new role aligns with the hard-line policy platform adopted at the Republican convention, where Trump officially became the party’s nominee on 19 July.
…The two candidates — whose campaign staff declined multiple interview requests — also seem to think very differently about the role of science. Although Clinton has described science and innovation as a foundation for the future, science funding seems to be an afterthought for Trump, says John Karsten, coordinator of the Center for Technology Innovation at the Brookings Institution, a think tank in Washington DC. Instead, the Republican has focused on issues such as national security, immigration and crumbling infrastructure. Climate change is one of the few science topics that has grabbed the campaign spotlight — in part because of Republican anger over Obama’s regulations to limit greenhouse-gas emissions from power plants, vehicles and oil and gas development. Clinton’s climate and energy proposals would largely maintain the current course; by contrast, in a major policy speech on 26 May, Trump promised to roll back Obama’s “totalitarian” regulations and withdraw the United States from the Paris climate agreement. Trump, who has long denied mainstream climate science, also said that his administration will focus on “real environmental challenges, not phony ones”.
