Signature drives
Getting a citizen-initiated measure on the ballot requires resources, often in the form of campaign expenditures on signature gathering. Ballotpedia analyzes the costs associated with initiative petition drives using cost-per-required-signature (CPRS), a metric that measures the amount spent relative to the number of signatures required for the ballot initiative.
The chart below shows the average CPRS and the largest CPRS for the years from 2014 through 2025. Click the year in the first column to access that year's data.

Media endorsements

What is a media editorial board endorsement? An editorial board is a group of editors at a news organization that writes editorials expressing the publication’s official opinion on public issues, candidates, and ballot measures. An editorial board endorsement from opinion columns, letters to the editor, or other articles that express an individual author’s views rather than the media outlet’s official stance.
