SIOUX FALLS, S.D. (AP) — Three Nebraska state legislators are lending their voices of support to a South Dakota constitutional amendment that would remove candidates’ party affiliations from primary and general election ballots.

Nebraska has a nonpartisan, one-chamber legislature, in which Republican and Democratic candidates run against each other in primaries and the top vote-getters advance to the general election.

Nebraska Speaker of the Legislature Galen Hadley, a Republican, says the system has worked well there for nearly 80 years, as it puts ideas ahead of affiliation. Instead of party leaders and caucuses setting agendas, bill sponsors have to build their own coalitions.

The South Dakota Republican Party opposes the measure, saying that removing party affiliation from ballots denies voters of relevant information. The South Dakota Democratic Party has not taken an official stance.
