Americans are often in a hurry, always looking for ways to save time. Yet back in the olden days, whenever Americans held an election, the public had to wait until every ballot was tallied before an official announcement of the results. Though that remains the method for squeaker contests, election-day reporting outlets strive to stay ahead of the curve wherever possible. Enter the exit pollers. Henry sits down with Joe Lenski, Executive Vice President of the survey research firm SSRS and co-director of The Voter Poll. Joe's here to explain how his team goes about sampling actual ballot-casters so the American people can get quicker (yet still accurate) calls on election night. 

Plus, keeping predictive power in mind, Henry reverse-engineers the generic ballot from the past three midterm elections to gauge who will win the House tug-of-war in November. And we take in Susan Collins' clever pitch to her Red Sox country voters about Yankee Chuck Schumer's attempts to influence the contest in Maine.
