I’d say it’s a testament to the stability of the US political system, which is related to but not the same thing as their political establishment’s resistance to change. When I said “a set political system”, I meant more as opposed to France’s two kingdoms and five republics, the Ottoman Empire’s transition to modern Turkey or the Russian empire becoming the USSR. I don’t think not going through that kind of transformation can be called stagnation, though the US definitely suffers from that too.
And that’s a problem. Other countries modernize and improve their political systems. The US clings to archaic institutions like the electoral college.
