SUDS is joining forces with the Heinz Policy and Politics Club to bring you a night of election prediction excitement.
Think you can predict the 2016 Presidential Election? Find our Election Prediction Form here. Make a copy of it (online or offline). Follow the instructions on the bottom right portion of the sheet. And then email your submission by Friday, November 4th at 8pm to firstname.lastname@example.org (you can submit by email or by sharing the document inside Google Drive).
Here’s some guidance for tonight:
- Follow this link and navigate to “Download CSV of polls” at the bottom of the page, above the links to sponsored content: http://projects.fivethirtyeight.com/2016-election-forecast/ (For more polling data, and to better understand what you’re looking at, check out links below).
- Import the CSV into R, Python, Excel, whatever you like, and simplify the dataset to only the variables that are of greatest interest to you.
- Though you may explore different outcomes using any of the three scenarios FiveThirtyEight uses to estimate the vote (Polls-Plus, Polls-Only, and Now-Cast), be sure to include rows from only one of these labels in your analysis. The dataset will include approximately 9000 rows; thus, your analysis should include approximately one-third of this total, or 3000 rows, per scenario.
- Pay special attention to the ‘rawpoll’ and ‘adjpoll’ columns, which give figures presented before and after FiveThirtyEight weighting was applied. Based on the resources below and your own intuition, decide if your interpretation of the raw data would differ from the ‘adjusted’ poll numbers in the dataset.
- Fill out the entry form (instructions on the bottom right) with your predictions and submit!
How to understand the polls + R polls-specific tutorials + more polling data:
- A User’s Guide To FiveThirtyEight’s 2016 General Election Forecast
- Get started with this fascinating piece that shows how different pollsters can arrive at varying conclusions – even using the same raw data.
- Read through a recent post by Peter Ellis, a professional statistician based in New Zealand. While the exact proprietary methodology that FiveThirtyEight employs remains a mystery, Ellis’ overview does touch on the apparent effect of grades assigned by Nate Silver and his team of data whizzes on weighting and distribution of the data.

Guiding Questions and Other Areas to Explore
- Take a look at the historical electoral college maps at 270towin.com and use them as references in your answers to the following questions.
- Taking into account the national and state-by-state polling Hillary Clinton has held the edge in national polling since the first presidential debate a month ago, but her lead looks to be dipping – and polls have not yet caught up to the news that the FBI discovered “pertinent” emails while investigating Anthony Weiner in an unrelated case. Which maps can you produce that result in a victory for Donald Trump?
- The last candidate to win 400 electoral votes was George H.W. Bush, who defeated Democratic challenger Michael Dukakis by a margin of 426-111 in 1988. (Dukakis won only 10 states, including his home state of Massachusetts, and the District of Columbia.) Can you plot out a path to 400 for either candidate? Which path do you think seems more likely, and why?
- Per your reading of the polls, where does Hillary Clinton have the best chance of “turning a red state blue” (i.e., winning a state that voted for Mitt Romney in 2012)?
- Conversely, which states that voted for Barack Obama in 2012 seem most likely to move into the Republican column and cast their share of the electoral vote for Donald Trump?
- Looking back at the last 24 years (since Bill Clinton was first elected in 1992), are there any general regional changes you can pinpoint? What is your hypothesis for these shifts?
- It has been 48 years since a third party candidate last won a state and carried its electoral votes. (Consult the maps for more on the pivotal 1968 election, and read more on the staunchly segregationist campaign George Wallace ran here.) This year, Libertarian Gary Johnson appears primed to capture at least five percent of the popular vote nationally, but it is Evan McMullin, a conservative, #NeverTrump flagbearer running as an American Independent, who stands a reasonable chance at defeating both Trump and Clinton in Utah. (His Mormon background in a predominantly Mormon state is crucial to understanding his viability there.) How would you assess McMullin’s chances in the Beehive State? Are you willing to venture a guess that he will win its six electoral votes?
