Some Sanders supporters have said they will vote for Stein if the Vermont senator loses the Democratic presidential nomination to former Secretary of State Hillary Clinton. In the U.S. Senate, Sanders is an independent and many of his supporters are newly registered to the party. They may not have a lot of party allegiance and vote for Stein.

Although the Green Party has existed as a political group in Wyoming since 1996, it’s not currently recognized by the Wyoming Secretary of State’s office. To get on the primary election ballot, the party would have to collect over 3,300 signatures to get on the ballot by June 1.

Haggerty said there is not enough time for a successful petition drive. So members are trying the next best thing: to get Stein listed as an independent for the Nov. 8 general election. That gives the party more time — until Aug. 29 — to collect signatures.

Stein will need 3,302 signatures to be on the ballot as an independent, said Kai Schon, state election director.

The Green Party is more left-of-center than the Democratic Party. But Haggerty said the party has had an appeal in Wyoming, one of the country’s most conservative states, since the turn of the century.
