Interesting insight in the newly released Senate Intel Report Volume 4 Review of the Intel Community...Open source was not sufficiently integrated into intelligence in the lead up to election 2016. intelligence.senate.gov/sites/default/… 
Also interesting: how Russia hit the seam against U.S. Intel community by exploiting bureaucratic divide between foreign & domestic. This still plagues defense of election 2020, how can we defend when we can't discuss the candidates?
the consensus is:
as for the rest of the report, can't decide which I like more page 73, or
page 110 which is pretty great too....😉
