I would argue that this is not the end of your country's democracy and that in 2028 a new president will be elected.

You'll have a new president in 2028, be it Vance, Shapiro, or Oprah Winfrey. Either way, it won't be DJT.

I am pretty sure the US will have elections in 2028. But Trump was almost successful in overturning the 2020 election.

Now, with additional concentration of power, that increases the possibility of a successful overturning (in favor of a new conservative candidate), or simply a biased election.

Dictatorships often have elections and are supposedly democratic. The question is whether those elections reflect the genuine, informed self-interest of the people.
