Passage Summary: Most reporters liked the current leader, and because the challenger got more bad press than the leader did, the reporters must have been biased in their work.

Conclusion: Reporters allowed their personal political biases to influence the way they covered the news.

Reasoning: The vast majority of reporters voted for the incumbent, and news coverage of the challenger was significantly more negative than coverage of the incumbent.

Analysis: The argument suffers from a classic 'correlation vs. causation' flaw by assuming that the disparity in negative coverage is caused by the reporters' voting preferences. It ignores the possibility that the challenger simply performed poorly or engaged in more 'newsworthy' negative behavior than the incumbent. To find the flaw, look for an answer that points out the author's failure to consider that the content of the news might actually reflect the reality of the candidates' actions. Perhaps the challenger was just having a very bad week, every week.
