Campaign finance requirements govern how much money candidates may receive from individuals and organizations, how often they must report those contributions, and how much individuals, organizations, and political entities may contribute to campaigns.
While campaign finance is not the only factor in electoral outcomes, successful fundraising can provide a candidate with advantages during a campaign. Fundraising can also indicate party momentum.
