The group Represent South Dakota met the November 6 deadline for submitting petition signatures to the Office of the Secretary of State to add a constitutional amendment to the 2018 ballot.

The amendment would tighten campaign finance and lobbying restrictions, create an independent ethics commission, and require laws changing the ballot question process to pass a public vote.

House speaker Mark Mickelson also met the deadline to turn in petition signatures for an initiative that would ban out-of-state political contributions for ballot questions, affecting groups such as Represent South Dakota.

The Office of the Secretary of State will conduct a random sampling of the signatures to determine their validity.
