Each line is a share of all registered voters (party enrollment). From 2007 on the counts are active voters unless inactive voters are added; earlier files don’t state voter status. The 1954–1970 unenrolled share is derived. A minor party appears in every report that lists enrollments for it, including years when it was not ballot-qualified (small residual counts). Districts use today’s lines: exact from the Secretary of State’s ward and precinct rows for reports since November 2022, and apportioned by 2020 population for earlier reports.
