Throughout the presidential debates, certain words (change, maverick) and phrases (my friends, Joe six-pack) used by the candidates have driven post-debate conversation. Last night, “Joe the Plumber” from Ohio, also known as Joe Wurzelbacher, found himself unwittingly added to the conversation. During a discussion about tax policy, the candidates referred to Joe at least 20 times, subsequently driving discussion and debate among bloggers. With fewer than three weeks until the election, it will be interesting to see if Joe’s story has legs.
