campaign summary
Each day, we gather news articles and TV clips, as well as metadata like estimated sentiment and audience size for each piece of media. We then search that content for mentions of candidates in our database. We also use the Google Custom Search API to identify search results matching the candidates in our database. This table summarizes the media data we’ve collected for each campaign.

Description
campaign id
Unique ID maintained by Deck representing a specific campaign.
We define a campaign as an instance of a specific candidate running for a specific office or party nomination.
If the same candidate ran in a primary and general election in both 2018 and 2020, they would have four campaign entries across those contests.
google search result count
The most recent number of Google search results returned for a query based on a given campaign.
If a campaign’s election was in the past, these results are benchmarked to the day before that campaign’s election date. If the campaign’s election is in the future, these results are current.
online news article count
The total number of news articles related to a given campaign, as surfaced through data we’ve collected from Aylien.
If a campaign’s election was in the past, these results are benchmarked to the day before that campaign’s election date. If the campaign’s election is in the future, these results are current.
online news sentiment index
The average sentiment derived from news articles about a given campaign (weighted by estimated audience size), as surfaced through data we’ve collected from Aylien.
A value of -1 indicates negative coverage, 0 indicates neutral coverage, and 1 indicates positive coverage.
