Final answer:
During the 2012 US Presidential Debate, Obama and Romney used three logical/rhetorical fallacies: hasty generalization, circular argument, and false dilemma.
Step-by-step explanation:
During the 2012 US Presidential Debate between President Barack Obama and Mitt Romney, there were three logical/rhetorical errors used by the candidates. The first fallacy is a hasty generalization, which is a conclusion based on insufficient evidence. An example of this is when Romney made remarks about the 47 percent, which hurt his position among poor Americans and those who sympathized with them. The second fallacy is a circular argument, which is when the conclusion is included in the premise. This can be seen when Obama used his bailout of the auto industry to appeal to voters in Michigan and Ohio. The third fallacy is a false dilemma, which is when only two options are presented as possible when there are actually more. This can be seen when both candidates made claims about their opponent's healthcare program, presenting it as either good or bad, without acknowledging the complexities of the issue.
