I will absolutely not hold Hillary to a different standard then you do Trump. If there's an investigation and it doesn't lead to charges it's a hoax. That's the Trump standard. So we have had the email server hoax, Benghazi hoax, whitewater hoax, Vince foster and seth rich hoaxes, Clinton foundation hoax etc. The email hoax most likely changed the election winner. According to little thethe that's a coup.
If you think Hillary should have been charged thats fine. I think Trump should have been charged for the Tryump university scam, or his various charity scams, or obstruction of justice of the Mueller investigation, or his tax/ insurance scheme, and hisnsoliciting election fraud in Georgia. The problem with most of these is you need to be able to show intent and prosecutors dont want to bring a case unless it's a slam dunk.
As for your other claims. There is no evidence she destroyed subpoenas evidence or that she ordered it. You can think it all you want but there has to be evidence. As for the polls they were 100% right nationally. Hillary was leading by 2% and won by 2.1%.
