This is a vice of Democracy, one which Russia and China do not share.
Unfortunately it's also the one that can best protect civil liberties, at least if said liberties exist within a constitution whose protection of which relies on someone/something outside the primary legislature.
In most Democracies you can see civil liberties are gradually eroded when ultimate authority rests in the legislature (house of representatives/house of commons/lower house, etcetera), meaning any protections afforded by something like a constitution are effectively worthless as they can be overridden by whoever assumes a majority in that body. The 2nd amendment could've been reworded or outright removed by now if all it took to get rid of it was a simple majority in the house and senate, but since the president also has to consent at the end to signing it, there's effectively 3 layers of protection.
Democracy works best when power isn't centralised in a single body (creating a Frankenstein king) but it's also the most frustrating when power
isn't since it slows things down massively.
One of the motives behind, say, France in 1848 to do such a thing was the belief it'd avoid emotions factoring into the creation of laws (lmao) but it also consequently enabled for itself to be overthrown since it allowed for the government to take away universal suffrage with a measly vote.

>also restrict voting rights to cement the illusion the guy you don't like isn't popular
You can see in my original post about how the left/right do thing differently. Despite wanting to empower the position of president and stay in office, effectively become a king in all but name, he was still doing so under the purview of the law. It was only once the government violated the constitution (removing universal suffrage in July 1851) did he gain the popular support to act.
TLDR: The vice of democracy (mostly America, other nations have shit democracies such as Germany) is also what best protects the people, assuming there's anything to protect. Having complex, stifling democracy + no civil liberties = living hell. Also civil liberties + supreme authority in single body = tantamount to no civil liberties.
