"None of the Above" will still be an option, but I doubt that any "Body" will have delegates in the GPUS Convention just two months and change from now.
As of this moment, Ventura. Is. Not. A. Candidate.
The rumors were flying a year and a half ago, and The Body denied that he was in the running for the GPUS nomination. He hasn't formally declared even now. If he had announced last spring or summer, put together an organization, and filed the appropriate paperwork, he would at least be a candidate.
Would he be a viable candidate? Plenty of Greens said last year, via social media and otherwise, that they would not support his quest for the nomination, given his Libertarian leanings. What these people forget is how much the Green and Libertarian platforms have in common, even if the core philosophies beneath those platforms are quite different.
My hope is that Ventura will meet with the candidates and head up the street team for the eventual nominee. As cool as it was to have Cornel West stumping for Jill Stein in 2016, Dr. West does not have the name recognition that Ventura enjoys. It might even lead to other celebrities helping us out, including not just occasional Green Susan Sarandon but those who have thrown their support behind the Movement for a People's Party (e.g., John Cusack). I don't foresee the Green campaign garnering as much celebrity support as Nader/LaDuke 2000 did (Eddie Vedder, Patti Smith, among many others), but, given the way 2020 has gone thus far, I may yet be proven wrong.
