From Green presidential candidate Jill Stein’s campaign website, July 9th, 2016:
We have repeatedly asked to meet with Senator Sanders to discuss the possibilities for collaboration to continue to build a progressive revolution in the US.
We have said we were willing to discuss a variety of cooperative approaches, including the possibility of creating a united ticket. At no point however have we simply offered that we would just step aside and give the Presidential nomination of the Green Party to Senator Sanders without serious discussions of issues and strategies. And of course, ultimately the nomination decision rests in the hands of the delegates to the Green Party convention, though most of them are pledged to Jill Stein.
However, the offer of a joint ticket was conditioned on discussing and agreeing on a joint program moving forward. We have always been clear that the path to a progressive revolution does not go through the Democratic Party, a position that Senator Sanders had shared through most of his political career. And while we agree with Senator Sanders on many issues, including both analysis and solutions, there are also some significant differences that would have to be addressed. This starts with foreign policy and the role of the US military, but includes specific domestic issues including the abolition of student debt and the need to transition to 100% clean renewable energy by 2030.
