Voters in Republican-majority South Dakota will decide this fall whether to abandon partisan primaries and make contests open to all candidates regardless of party affiliation. The top two vote-getters in each race would then face off in general elections.

Secretary of State Monae Johnson’s office said Tuesday that it has certified the proposed constitutional amendment for the November ballot. The South Dakota Open Primaries group submitted the necessary petition signatures earlier this month.

Other initiatives that will appear on the ballot include measures to protect abortion rights and to repeal the state grocery tax. A measure awaiting validation would legalize recreational marijuana.

The state’s candidates in gubernatorial, congressional, legislative and county races currently compete in partisan primaries. If voters approve it, the amendment would have them compete in a unified primary instead.
