Latest voter registration figures show 18 Oklahomans registered as Americans Elect. Ziriax said their registration will be transferred to independent.
Americans Elect, a nonprofit group, had planned in June to hold the first-ever online nominating convention to select a president-and-vice president ticket.
To obtain party status and have names placed on state ballots, a political party has to get signatures of registered voters that equal at least 5 percent of the votes cast for the office at the top of the ticket. Political parties this year had to turn in petitions with at least 51,739 valid signatures.
