Science advocates are hoping the new Democratic majority in both houses of Congress will team up with President-elect Joe Biden "to move forward in ways that are transformational and not incremental." The narrow edge in the Senate will make it easier for Biden to win confirmation of his appointees and for Congress to revoke controversial rules finalized in the final 5 months of President Donald Trump's administration. It could also help Democrats enact promised legislation aimed at curbing climate change and boosting federal investments in research, infrastructure, and public health. But a narrowly divided and highly polarized Congress will likely constrain efforts to realize the most ambitious proposals put forward by policymakers and advocacy groups. And Democrats could have as little as 2 years to exercise their expanded powers if the midterm elections in November 2022 gives Republicans a chance to regain one or two bodies.

科学主义者希望在国会两院的民主党新多数将组队与总统当选人拜登“继续前进，是变革，而不是渐进的方式。” 参议院的狭edge优势将使拜登更容易赢得其任命的确认，并使国会撤销在唐纳德·特朗普总统执政的最后5个月中最终确定的有争议的规则。它还可以帮助民主党制定有前途的立法，旨在遏制气候变化并促进联邦政府在研究，基础设施和公共卫生方面的投资。但是，一个分裂程度极高且两极分化的国会很可能会限制实现政策制定者和倡导团体提出的最雄心勃勃的提案的努力。
