I don't doubt it. Even to an outsider there is a obvious economic divide between blue and red states and I am sure both parties exploit that to some extent.
Judging from what I have seen of the foreign reach of "US" politics I am certain there is a lot of dark money and influence going around beyond any official numbers. I have doubts if those sorts of operations have any influence on the swing voters that were required for a victory. It seems more likely their needs were simply ignored.

I personally suspect, but can't really know, that this is what explains the dysfunctional state of US politics. It is simply too big a target for corruption for it to ever be able to operate effectively. You can see that many US states seem to have much more effective governance than the Feds despite having nominally the same two major parties. I also think this explains why Australia is better run than the USA, and why New Zealand and Norway are better run than Australia.
I wonder if there is even that much dark money is circulating beyond official numbers. Why would they bother, given that they have the legal loophole of PACs, Super PACs, and 501(c) groups.
It already seems so easy to throw money at a candidate if you wanted to, without even needing to do it behind closed doors.
