Understanding why Republicans have challenged funding for the NSF

Lack of Congressional support in funding the National Science Foundation has often been justified by the party's interest in cutting federal deficits and reducing waste for seemingly frivolous research projects. However, an analysis of NSF grant data from 1992 to 2018 shows that awards were given to Democratic constituencies at disproportionately higher rates than to Republican ones, despite a lack of evidence of partisanship in proposal reviews.
