Stacey "Stace" Nelson is an American politician, law enforcement officer, and retired Naval Criminal Investigative Service special agent[1] who served as a member of both chambers of the South Dakota Legislature.

During Senator Nelson's subsequent speech [14] he pointed out he was not running for the position and encouraged delegates to return the GOP back to its moral compass.

[17] In removing Nelson from the caucus, House Majority Leader David Lust stated "I am not going to condone the conduct he engaged in toward another member of the Legislature very publicly.

"[18] In 2013 Stace Nelson was named as an unindicted co-conspirator in a case where the State of South Dakota prosecuted Dan Willard for political robodialed phone calls that were made without a disclaimer.

"This case is stale and focuses upon conduct alleged to have occurred prior to the 2012 general election," Second Circuit Court Judge Mark Salter wrote.
