Sen. Bernie Sanders, who is expected to end his quest for the Democratic presidential nomination within days, has been offered to run as the Green Party candidate.
Jill Stein, the presumptive Green Party presidential nominee,
told London's Guardian newspaper she would be willing to step aside if Sanders wants to take her place.
"I've invited Bernie to sit down explore collaboration — everything is on the table. If he saw that you can't have a revolutionary campaign in a counter-revolutionary party, he'd be welcomed to the Green party. He could lead the ticket and build a political movement," Stein said.
Stein, a former Massachusetts doctor, made the offer in an email to Sanders but has not yet received a response.
She said many of Sanders' young supporters are now backing the Green Party rather than turn to Hillary Clinton, the presumptive Democratic nominee.
"I'm not holding my breath but I'm not ruling it out that we can bring out 43 million young people into this election. It's been a wild election; every rule in the playbook has been tossed out," she told the Guardian.
