The Arkansas Green Party expects to begin its 2008 petition for ballot status on July 24. Currently, there are no qualified parties on the ballot in Arkansas except for the two major parties. Parties set their own petitioning period, but must get the job done in only 60 days. 10,000 valid signatures are required.
Parties that only wish to be on for president only need 1,000, and can take as long as they wish.
UPDATE: The Green petition will start on July 30.
