My advice is to actually listen to Democrats close to the campaign (and/or with previous campaign experience). They aren't pulling a rope-a-dope. They are telling us publicly that despite the changed landscape, we still have an uphill battle, and that momentum in Democratic circles != being (comfortably?) ahead. We need to get more independent/undecided/unlikely voters to turn out to win in key states.
There have been numerous quotes in this thread but each time they were written off as not knowing what they are talking about because they were on Clinton's campaign or just trying to run the score up, etc. That is why your disdain/distrust for every Nate Silver tweet is so ironic.
And here's a clear example that Nate did include the Dems +6 poll in his model contrary to what you insinuated:
Or they aren’t trying to repeat 2016 and don’t want to get complacent in a close race. I’m not saying they are up by a ton. In todays day and age every election is gonna be somewhat close
Silver isn’t infallable if you want to believe him over others fine but there is no evidence that he is better at it then everyone else
The actions of Trump and his campaign lately aren’t that of someone who thinks they are up imo
