Tulsi Gabbard would surely be the best candidate by a mile to stand against Trump. An intelligent, articulate, educated and good looking young woman that speaks common sense.
Plus, she has been on two tours of duty on Iraq/Afghanistan or some other a**hole place.
Even though she is from Hawaii (not like Obama who was from Kenya or whatever the Orange Man said) she would be, IMO, a huge VP asset.
It won't happen, but it would be interesting to have her in a debate against the Orange Man where he pulled some medical exemptions when his number was called ("my foot hurts") against her who volunteered to put her butt into a dangerous place.
The Orange Man would fill his Depends (both sides) if he had to debate her.
