Tulsi Gabbard - I agree would be the biggest competitor to Trump , she has voter appeal in many ways -  but she is NOT as she purports to be , wolf in sheeps clothing ,she is fairly commie leaning herself ,amongst other stuff Hillary , using her control over the DNC ,stunted her run as she was too much competition and be harder to control Wouldnt be surprised to see Tulsi run as an Independant candidate
