US politics is structurally messed up and there will be more escalating drama in the coming years/decades that will definitely leak internationally. With mechanical issues like the electoral college being deeply flawed, to more innate issues of the system like the two party system reducing the entirety of politics in the USA to an adversarial binary, it will just get more polarized and ensure the disenfranchisement of even more people than now. This is a minor win in a sinking ship, IMO.
The thing that will leak internationally is the rapid and unsustainable increase in the US debt. The political shuffling is just rearranging the deck chairs in comparison.
