@edgarblythe,
Possibly, however, Tulsi has not responded any better than Clinton did in bringing it up.
It's really not outside of the possibility for Tulsi to go at a third party.
Moreover, right-wing groups like some of the alt-right wing groups have been showing support for her.
Clinton could be trying out a possible run, (she is hardly disgraced), she would certainly do better than Trump.
Personally I doubt either one of the above listed possibles.
