Which logical fallacy is used in the text?
Don't be deceived by Susan McKee's articles on rural, blue-collar workers. Her husband is a fancy investment banker, so she can't possibly understand their situation.

 - guilt by association: a negative association intended to discredit someone or something
 - straw man: a misrepresentation of an opponent's position that makes it easier to argue against
 - bandwagon fallacy: the assumption that the popular choice is automatically correct
The text argues that Susan McKee can't understand rural, blue-collar workers because she is associated with an urban newspaper. However, where Susan works doesn't necessarily indicate anything about her ability to empathize. This illustrates a type of logical fallacy known as guilt by association.
