Below is a table showing average campaign expenditures, source of funding, and reelection rates for congressional campaigns in a recent election cycle:
| Chamber and Candidate Type | Average Campaign Expenditures ($) | Percentage of Funding from PACs (%) | Reelection Rate (%) |
|---|---|---|---|
| House Incumbents | 1,850,000 | 42 | 93 |
| House Challengers | 420,000 | 8 | — |
| Senate Incumbents | 12,400,000 | 18 | 82 |
| Senate Challengers | 2,100,000 | 5 | — |
Based on the table and your knowledge of United States campaigns and elections, which of the following statements best explains the differences in campaign expenditures, PAC funding, and reelection rates between the House of Representatives and the Senate?
- Senate campaigns are significantly more expensive, requiring candidates to rely more heavily on individual donors than on PACs, and senators represent entire states that are more politically diverse and cannot be gerrymandered, leading to lower reelection rates than in the House.Cevap
- BHouse districts are gerrymandered by state legislatures to create safe seats for incumbents, whereas Senate districts are periodically redrawn after the census to ensure that both major parties remain competitive across the entire state.
- CThe Constitution grants the House of Representatives the sole power to initiate revenue bills, which prompts political action committees to concentrate their contributions on House incumbents who control federal appropriations.
- DHouse incumbents adopt the delegate model of representation to satisfy local PAC demands, whereas senators act as trustees, allowing them to ignore campaign finance pressures due to their longer six-year terms.
Cevap
Senate campaigns are significantly more expensive, requiring candidates to rely more heavily on individual donors than on PACs, and senators represent entire states that are more politically diverse and cannot be gerrymandered, leading to lower reelection rates than in the House.
The correct answer accurately identifies that Senate races are much more expensive than House races, which means political action committee (PAC) contributions—which are subject to strict federal limits—constitute a smaller percentage of a Senate candidate's overall campaign budget compared to a House candidate's. Furthermore, senators represent entire states rather than single districts, meaning their constituencies are more diverse, cannot be gerrymandered, and attract high-profile challengers, resulting in lower reelection rates.
