Trump would be crazy to pick Stanley.
I saw him on CBS Sunday Morning a few years ago. McChrystal is a notorious gun grabber, saying that “assault weapons” (semi-automatic rifles) are weapons of war, they should be banned from “civilian” ownership, etc. The guy has a fascist streak.
He and General Petraeus recently hooked up with that other gun grabber Mark Kelly.
Just say NO!
As far as I can tell, the only General who is seriously being vetted for VP by Trump is Flynn. Flynn was and remains a strong and effective critic of the Obama/Clinton debacles in Libya and Syria, but I have no idea where he stands on domestic issues like immigration, guns, etc.
