South Dakota nonpartisan groups are supporting a state constitutional amendment to remove candidate party affiliations from primary and general election ballots.
AARP South Dakota and the League of Women Voters of South Dakota say passing the amendment would help give 115,000 independent voters an equal voice in the electoral process.
If approved in the November election, the amendment would establish a nonpartisan primary that would send the top vote-getters to the general election.
It wouldn’t apply to presidential races.
Supporters say the measure would help broaden the participating voter base because many elections now are effectively decided in partisan primaries closed to independent voters.
Top Republicans including Gov. Dennis Daugaard, U.S. Senator John Thune and Congresswoman Kristi Noem are opposing the amendment.
