Prop stands for Proposition, a political abbreviation.

Example: Prop 50 asked California voters in 2025 to approve new congressional district maps.

Usage notes

California's Prop 13 of 1978, which capped property tax increases, is among the best-known ballot measures in US history and inspired tax revolts in other states. Measures reach the ballot by citizen petition or by legislative referral. Other states use labels such as "Question", "Amendment", "Measure" or "Issue" instead of Prop.
