Interestingly enough Democrats raised $2.3B and Republicans raised $0.2B last presidential election cycle (1), it’s clear that the more monied party are the Democrats, my take here is that the Republicans are either more grassroots and don’t need to convince as many Americans to vote for them or they are far more efficient with capital during campaigns. PAC spending was also within 9.7% of one another in 2024 (2).
