Are you not doing as exactly as you are highlighting?
If there were underlying forces at work that were foreign would that not mean it wasn't fair and square?
Citizens United vs FEC[1] unfortunate decision in 2011 led to infusions of foreign funds[2] that outnumber what US citizens are legally allowed to contribute. Too much money and now foreign money that is the real problem, it reared it's ugly head in 2016 no matter who won.
We have to backtrack on Citizens United vs the FEC decision or else foreign countries and oligarchs will be deciding every election. If that becomes the norm, it was a good run for the United States but it will be ending.
