No, and you won't see any either, even Sanders is a noshow. Jill Stein made it clear where she stands--Go girl!
Obama won't as it would be suicide for some career after he leaves office. HRC can't as she owed them all too much money and favors. She loves fracking and pipelines and Big Oil. As I have stated elsewhere (and here), this is cultural genocide.
What all these profiteers fail to realize or don't care since they are all in the moment is the contamination of our water supply (oceans and fresh) has no substitute. The entire human race and eco system needs water to survive--Insect, birds, animals, all plant life, our food sources and when that is gone/destroyed, that is the end of all life on this planet.
Oh, I answered that myself. They just don't care.
