Arguments

Pro

Yes on Prop. 39 gives California a BIPARTISAN solution for VOTER ID. Supported by a solid majority of Democratic, Independent and Republican voters. Increases trust and confidence in our elections.

Con

No on Prop. 39. This would advance Trump’s voter suppression agenda by adding costly, unnecessary barriers that could block eligible California voters, expose personal information to identity theft, and waste hundreds of millions in taxpayer dollars. Don’t let MAGA billionaires decide which voters count. Vote No.
