From South Carolina Libertarian Party here.
On May 7, 2016, the South Carolina Libertarian Party held a straw poll with the members that were present as the last event in its Nomination Convention.
The results were:
Gary Johnson – 12 votes
Austin Petersen – 10 Votes
Marc Feldman – 1 Vote
Jack Robinson – 3 Votes
[Jack Robinson is a resident of South Carolina who is also seeking the Libertarian nomination for US President]
John McAffee did not receive any votes.
While the results of the straw poll are NOT binding on the Delegates that will represent South Carolina at the Libertarian National Convention in Orlando, State Chairman Stewart Flood and State Vice Chairman Travis McCurry added a little twist just prior to the taking of the poll. They said since they were undecided about whom they should support at the National Convention, they would vote for the winner of the straw poll in the first round at the National Convention.
So, Gary Johnson will have at least two votes from South Carolina in the first round of voting.
