It’s important for students to stay politically informed, but often newspaper articles can be partisan, needlessly inflammatory, or simply not explain what they are reporting on.  FiveThirtyEight is a service that uses statistics to explain political happenings as well as providing explanatory articles on things like the electoral college.  Interactive activities allow students to adjust things like voter turnout to influence the outcome of elections.
