Let me clear that up for you - Clinton is not insane - Trump IS insane. No world war with sane Clinton - likely World War Three with insane Trump. If you are dead, you won't need healthcare and it won't matter who is on the Supreme Court.
...hmm...let me clear that up. Clinton may not be insane by your definition, but she IS criminal and leads a trail of scandals and corruption. She got a rapist acquitted; he raped a 12 year old girl so violently that they had to sew up her insides and it is reported she laughed about it. The list continues with Vince Foster, Whitewater, Fast 'n Furious, Huma Abedin, Benghazi, e-mails, Clinton Foundation, etc., etc. Perhaps it's a matter of perspective, but I see Clinton as criminally insane. She IS responsible for the rise of ISIS and 4 dead Americans. So, I'm not so sure it is safe to assume she wouldn't catapult us into WWIII.
I would STRONGLY suggest you see the movie "Hillary's America", perhaps your definition of 'insane' will be somewhat different.
