Which group provides the largest share of money to congressional campaigns?

• A. PACs
• B. Major corporations
• C. Individuals
• D. Unions

Answer: (C)

The main idea is about who funds congressional campaigns the most. Individuals provide the largest share of money because there are many more individual donors than organized groups, and individual contributions come from a broad base of voters, often giving at various levels. While PACs do pool donations and unions have money they can contribute, direct contributions from corporations to campaigns are not allowed, and unions and corporations typically influence through PACs or independent expenditures rather than direct candidate funding. Because the collective impact of thousands of individual donors outweighs the total from PACs and other groups, individuals end up supplying the largest share of campaign money.
