I used to share your opinion, but were to the point where it’s difficult to say it’s dumb luck. Look at the amount of change and impact they’ve had on the country in such a short period - it feels wrong to say that chance/luck/whatever rather than intentional, planned, and skilled manipulation.
But even with the benefit of hindsight, it's not always clear if a politician's impact was good or bad: people over here are debating how good Angela Merkel really was, and she's been out of office for 4 years (after 16 in power).
It's well planned, but the same subtlety as flying planes into a skyscraper.
The skyscraper is the size / scope / power of the US Federal Government (although incidentally it's also housing the US Constitution). And the planes are the entirely unqualified loyalists and useful idiots appointed to top positions of power.
