From the Database Intro:
NCSL’s Ballot Measures database includes all statewide ballot measures for more than a century. The database is searchable by topic area, with options such as abortion, bond measures, criminal justice, education, elections, health, labor and employment, natural resources, tax and revenues, transportation and more. The database is updated as new ballot measures qualify to be on the ballot. On election night, each entry is updated with “pass” or “fail.”
This NCSL Blog post provides a look at some of the 147 ballot measures that will be voted on this year. Details about all of these measures can be found by searching the database.
