Primary voters in twelve states (and American Samoa) head to the polls on Super Tuesday — and media expectations are high. Our collaborators at the data news site FiveThirtyEight have a politics podcast, and this week their look at Super Tuesday explains how to read the Super Tuesday results, including media declarations of “inevitability” and “momentum.” Plus: why Donald Trump’s candidacy has thrown forecasting models into disarray. We play two long excerpts from the podcast, which you can listen to in its entirety here.
