Wearing the uniform will be a major detriment to her in democrat circles. The democrats dont mind having a few token veterans scattered about, but they sure as hell don't want one as their nominee.
John Kerry was the last one they put up, but that was a different democrat party and only a few years removed from 9/11. Keep in mind Kerry had to basically call him fellow service members war criminals and murders to get the nod.
We know from 2016 that the democrats dont have a primary process that nominates their candidate. The DNC is the governing body and the party bosses chose their candidate in a series of backroom deals and the primary is just to give the illusion of control by the people. They even have super delegates who can override the vote so they are surprising honest about their process. At the end of the day, these party bosses who will decide the nominee absolutely hate the military and veterans and they will not tolerate a veteran as their nominee.
I hope Bannon is putting together funding for a Tulsi third party run.
