On the East Coast, New York mayoral candidate Anthony Weiner confronted new revelations of more inappropriate sexting he did after leaving Congress (and introduced America to his alias, "Carlos Danger.")

To explain is Mark Sachleben, professor of political science at Shippensburg University in Pennsylvania, and co-editor of the upcoming book, "Scandal! An Interdisciplinary Approach to the Consequences, Outcomes, and Significance of Political Scandals."
