Just assume that where I don't quote, I agree pretty much entirely
You disagree that Hillary is to blame for Hillary's loss? So much for "the buck stops here." IMO it is her fault that things were close enough in the first place to allow Comey and Wikileaks to tip the scale.
As for the effect of Comey's late-October announcement that the email investigation was back on, I give you Nate Silver:

1. Yes. Elections are not simple things. I'm not going to say there weren't things she or her team could've done better either.
2. Please don't make me read Nate Silver

I can elaborate more on this elsewhere, but the dude has massive-tier garbage takes so much of the time. That doesn't rule him out in terms of actually turning up with a decent read occasionally, but not right this second for me (not a huge amount of time spare).
Anyway to link things back to the topic of this thread: "Hillary did nothing wrong and the election was stolen from her by wikileaks/Russia/Comey" would be an absolutely disastrous view for Democrats to take away from the 2016 election. For one thing even if it is perfectly accurate it is all pretty much beyond our control. The way we campaign, the candidate we nominate, those things we can control. And to say we cannot do better than we did in 2016 is just garbage.
I just want to stop you on the whole "Hillary did nothing wrong" thing. Because nobody said that. At least, I didn't say that. I'm not the Democratic Party, right? I'm not talking in abstract terms about what the Democratic Party should take away from 2016, I was exploring our views here on CFC about why the hacking of RNC emails is apparently worth some cheap shots. What the DNC should do vs. what I'm arguing are distinctly different things!
It's a problem, I feel, because it contributes to dismissing it as a strategy of interfering in a US election. The fact that the US (and UK) are involved in coups the world over aside for the moment (I do not believe multiple wrongs somehow make a karmic right in this context, I know some leftists that do), we should push back on
anything like this because it opens it up to it happening again against people we actually
want to win a nomination. It's not a slippery slope, because we're discussing something that has literally already-happened, to a candidate that right-leaning interests ironically probably have the
least objection to.
That's my worry. I've already seen what a constant media barrage can do to someone like Corbyn, here in the UK. Imagine adding something like a phone tapping scandal to that as well (which happened, but mainly affected Conservative interests, and therefore has had basically no ramifications or consequences of note).
