A new study published in Science challenges the conventional view that Democrats are uniformly the pro-science party. An analysis of federal science funding from 1980 to 2000 found that overall funding for science and research recipients tended to rise when Republicans controlled the White House or the House of Representatives, compared with periods when Democrats held those powers. The researchers examined spending across 171 funding recipients represented by 27 agencies, including the CDC, NASA, NIH, the NSF, the Department of Health and Human Services, the Department of Energy, and the research and development arm of the Department of Defense. During the period studied, the White House hosted three Democratic presidents and four Republican presidents, while the House changed hands three times under Democratic control and twice under Republican control. The analysis mapped the flow of dollars through the federal budget sausage factory to see where science spending actually landed across agencies and programs, rather than relying on broad party labels.
The study’s authors—Dashun Wang, a professor at Northwestern University, and Alexander Furnas, a research assistant professor at Kellogg—emphasize that the findings reflect historical patterns rather than current politics. They say the data suggest that science funding levels often fluctuated with the partisan composition of key levers of power in Washington, but the mechanisms behind those shifts are not fully explained by party allegiance alone. The researchers caution that the balance of scientific investment is mediated by a broad set of priorities, including the size of the overall federal budget, competing domestic programs, and the priorities of individual lawmakers who seek to shield or promote funding for particular agencies and programs.
Across the period analyzed, the recipients and agencies that benefited from higher funding under Republican control spanned the Defense Department’s research activities, the NIH, the NSF, NASA, and related science and health bodies. On average, science- and research-related recipients received about $150 million more when Republicans controlled the House and about $100 million more when a Republican occupied the White House. The gains were not uniform, however. The Department of Energy, an agency often at odds with fossil-fuel interests, received roughly one-third less funding when Republicans controlled the House than when Democrats did. The study also notes that the Senate generally exhibited more appetite for cuts to science budgets during GOP majorities, though many proposed reductions did not survive conference negotiations with a Republican-led House. These patterns, the authors say, emerged from parsing nearly four decades of spending, not from a single year or a single policy impulse.
The authors describe the findings as descriptive, not prescriptive, and they emphasize that the total federal budget dwarfs science outlays. They point out that discretionary spending—covering transportation, education, housing, social services, and science—constitutes about a quarter to a third of the overall budget in many years, with science representing a modest slice within that discretionary envelope. In the period under study, science funding varied roughly between about $120 billion and $225 billion annually, representing a small share of the final budget. Still, the authors note that the scale matters for institutions and communities that depend on federal dollars, including states with large research ecosystems and cities that host major centers like NASA and the CDC.
The study also touches on the political dynamics of the budget process. The authors explain that the president proposes a budget, but the actual appropriation occurs through Congress, where committees and party blocs bargain over numerous competing priorities. They highlight that the president’s leverage is limited by the risk of a government shutdown if Congress does not pass funding bills, which adds a powerful incentive for lawmakers to protect or reshape science investments during the appropriations process. The authors observe that the partisan fights for science funding often unfold behind closed doors as committees draft and reconcile bills, but they underscore that the evidence they present comes from concrete spending patterns rather than promises or political rhetoric.
What, if anything, explains why Republicans would be associated with higher science funding in the period studied? The authors suggest that the drivers are not reducible to a single cause. It may reflect a combination of targeted funding favors for specific agencies, the influence of states with strong science economies, and trade-offs in other areas that shape overall budgeting decisions. One possible interpretation is that Democrats, who favor broader social and safety-net programs, may face more competing priorities, requiring trade-offs that affect science dollars. The authors caution that their aim is to present the facts, not to advocate for a particular policy or to assert a universal rule about party alignment with scientific funding.
If the takeaways feel remote from today’s political climate, the authors note that their analysis describes a historical era. They acknowledge that more recent dynamics—such as shifts in how the Senate handles science funding, changes in the administration’s priorities, and evolving party coalitions—could produce different patterns in the future. Still, they point to ongoing instances in which Congress has acted to temper executive proposals that would sharply cut or reorganize science funding. In that sense, the authors say, bipartisan appropriations traditions can serve as a stabilizing force even amid sharp political disagreement.
Ultimately, the study challenges a simple narrative about party alignment and science policy. It shows that, at least in the late 20th century, Republican control of the White House or the House sometimes coincided with higher funding for major science agencies, while Democrats funded a broad array of programs at slightly different levels. The researchers emphasize that their conclusions are historical and that future dynamics will depend on a range of budgetary and political factors.
US politics dynamics around science funding remain in flux, but the analysis offers a data-driven reminder that the relationship between party control and science dollars is complex and context-dependent. For policymakers, institutions, and researchers relying on federal support, the findings underscore the importance of the appropriations process as the arena where funding for science is ultimately decided, even amid the broader debates that define modern American politics.
