As the midterm elections approached, the New York Times undertook an interesting experiment: It would conduct polling in dozens of House districts, showing users the results in real time. Partnering with Siena College’s polling team, the idea was that users would gain a better understanding of how poll results are dependent on vote models and the number of respondents by presenting the survey in a sort of election-night, watch-the-results-unfold format.
At the same time, of course, the team also generated a ton of poll results in districts that are important for control of the House. A ton of results. There were 90 separate House polls, including nearly 30 districts that were polled twice. CONT.
