But floating a run in 1988 and finally doing it in 2016 doesn't represent a good return on investment for the Soviets, whose own government collapsed in 1991.
And this article is attesting to millions being invested in Trump by the Russians. Even hugely successful spies for the Russians didn't rake in millions. Robert Hanssen was perhaps the worst of the worst spy for the Russians. An FBI agent, he fed the Russians highly sensitive, actionable information for over 20 years, and he was paid a grand total of just over $1m over those 20 years.
Trump also publicly professed to be a Democrat in the early 2000's, and everyone thought he was one up until just before his run in 2016. His past political donations went to Democrats all over the country by a pretty wide margin.
