Winning a U.S. presidential election hinges on a complex interplay of factors, among which campaign strategies, candidate credentials, media influence, public accessibility, socioeconomic contexts, and voter sentiment are key. Yet, the fundraising and resource allocation process is central to these dynamics—the driving force that propels these elements toward a more significant impact. Fundraising serves as both the lifeblood of the campaign machinery and a catalyst for enhancing the effectiveness of other campaign components. Consequently, extensive research has studied the correlation between financial backing in U.S. presidential campaigns and candidates' success. Although findings vary widely, a consensus has emerged around the essential role of funding in mounting a viable campaign. Divergences among studies, however, suggest that the sheer volume of funds raised does not consistently predict electoral success. This nuance became particularly evident in the 2016 and 2020 presidential campaigns, where the connection between campaign financing and the likelihood of victory appeared less direct, signalling a shift in campaign financing dynamics and evolving voter priorities.   On the other hand, the scale and nature of campaign funding reveal insights into voters’ preliminary preferences, political leanings, and a potential president's anticipated priorities and agenda. Campaign funding reflects the candidate's backing base and hints at the strategic tools and priorities the next administration might emphasise. This analysis thus examines the funding sources behind the Democratic and Republican presidential campaigns—the largest and most competitive contenders for the White House.
