One advantage that incumbents always have over challengers is which of the following?

• A. Their larger share of federal campaign monies.
• B. The political advantage of riding the president's coattails.
• C. Their use of free mailings, or franks.
• D. Their freedom from libelous laws.

Answer: (C)

The main idea here is that incumbents have a built-in, official campaign advantage: the franking privilege, which allows members of Congress to send mail to constituents without paying postage. This free mail capability makes it much easier for an officeholder to stay in voters’ sight, share what they’re doing, and promote their record without spending campaign funds. That consistent, cost-free outreach is a real, recurring edge that challengers don’t have. The other possibilities are not as reliable: fundraising can vary and isn’t guaranteed to favor incumbents; riding the president’s coattails depends on the political climate and isn’t universal; and libel laws apply to everyone, so incumbents aren’t exempt from them.
