Prop 0 refers to Proposition 0 in your jurisdiction, but voting details depend on the specific state, county, and the official ballot language. To give you accurate guidance, please share:

• Your location (state/ccounty)
• Whether Prop 0 is part of a statewide election or a local measure
• Whether you plan to vote in person or by mail

If you want a quick generic guide, here’s how to find up-to-date information:

• Check your state's official election website for the current ballot measures and their voting deadlines.
• Look up your county elections office for in-person polling places, hours, and any same-day registration options.
• Confirm registration deadlines and ballot mailing timelines on the state portal or secretary of state site.

I can pull precise dates and locations once you share your location.
