Passage Summary: Since politicians only give speeches to get elected, we can't trust what they say and should assume they are just being selfish.

Conclusion: Speeches made by political candidates are untrustworthy and driven by self-interest.

Reasoning: The primary goal of a politician delivering a speech is to win an election.

Analysis: The flaw here is the assumption that a person's motives dictate the truthfulness or reliability of their statements. While it is true that politicians want to get elected, that doesn't logically prove that their promises are 'unreliable' or that the content of the speech is purely selfish. A candidate might make a reliable promise specifically because they believe it is the best way to get elected. Look for an answer that points out the argument's failure to distinguish between the purpose of an action and the quality of its content.
