Trump won in 2016, but it cost him and the country dearly.
Hillary had a triumph of her own by causing Biden to become POTUS.
How did Trump winning “cost the country dearly”???
Can you expound on this? (It's not clear what you mean.)
Trump's victory in 2016 exposed the rot and the corruption in our government and in our institutions; if this be considered a "cost" to our country, then so be it. I consider it an exposé that most, if not all of it, had become nothing more than a pack of lies.
The soft coup that took place in November of 2020 simply confirmed it; we're a banana republic.
