Which statement about political advertising is true?

• A. They are a cheap method of informing voters.
• B. They have long-lasting effects.
• C. They are massively effective and changing voters' minds.
• D. Candidates do not counter-advertise.

Answer: (C)

Advertising in campaigns can shape how voters see candidates and issues, especially when messages are memorable, well crafted, and repeated. This is why it’s reasonable to say that political ads can be massively effective and capable of changing minds in some races. The impact tends to be strongest among undecided voters or in tight contests, where a well-timed message can sway opinions or increase recall and perceived credibility of a candidate.

The other statements don’t hold up as broadly true. Political ads are not a cheap way to inform voters; they require substantial spending to reach enough people. Effects from ads are not usually long-lasting; they often fade unless messages are reinforced over time. And campaigns frequently use counter-advertising to respond to opponents, so the idea that candidates do not counter-advertise is inaccurate.
