The U.S. election is just around the corner — and this year the election will look much different than previous years. In the midst of the coronavirus pandemic, there are new questions arising around voter health and safety, ballot fraud and security, and voter suppression. There are now more ways to vote — in-person early voting, mail-in ballot, absentee voting, and same-day election polls. We may not even know the final results of the election until weeks later. Regardless of the outcome — this will be a history-making election. 

Data plays an important role in elections. Data provides voters with insights on the props and candidates running in their area. It can provide campaign officials with information citizens within their counties, states, and national and the issues they care about. Data is collected on the day of the election and shared with media outlets in real-time to communicate results to citizens quickly.
