Okay, so this is broadly true. Clinton's loss was so slight that changing any one of a number of things would have changed the result, and so you could blame any one of those things for being the 'critical factor'. But, more broadly... she should never have been in that position in the first place. None of them should have been critical factors! She was running against the most disliked presidential candidate in post-war American history, on the coat-tails of a largely popular incumbent with a good economic track-record given the context. It should have been a blowout.
Nope. 2016 was not like any previous election. America faced a foreign power directly interfering with their election. No campaign is equip to deal with something that has never happened before. No campaign ever had to deal with the FBI dropping harmful news weeks before the election.
As for the rest of your post- I get it Hillary is evil, Bernie is the Messiah. How dare anyone question Bernie? See you still holding on to your 90% July claim, and now include Edwards.
Expect I'm not just question Bernie- I'm question his campaign. I'm question Russia. I'm question Trump. I'm questioning Trump. I question the USA that I grew up in that taught us hide under out school desk cause Russia was going to bomb us any day to Putin is a great guy, we should trust him over Hillary, Obama, Biden, Kerry, or McCain.
You talk about me not not learning from the 2016 campaign, yet here you are repeating the same rote, propaganda talking points from 2016.
It's 2017. More facts have come out. Every day, the Steele Dossier goes from being tinfoil, to being a legitimate check list of how the election was stolen by agent inside and outside the country. The manipulation of news, feeds, and bots is proven. Part of, not all, Bernie supporters got swept up in that.
Trump's Russia connections become clearer to the public every day. Did you not watch the recent G20 meeting with Putin? Nothing is normal with was is going on between Putin and Trump. People are reviewing voting counts and disturbing trends are coming to light- some vote machines were changed. Voters were purged.
Yet here you are- with the golden answer- Hillary is to blame. You've learned nothing since 2016.
