The whole idea is silly.  Tulsi has alienated herself from mainstream Democrat elites.  She is most definitely not part of the insiders club, and she would need to be. 
Also, taking part in protests only makes herself out to be a radical, not mainstream enough.  She acted mainstream, and somewhat conservative to get elected.  Now she has exposed herself to be a real lefty, and therefore should be concerned with getting elected again here, let alone for President.
