What you described is pretty much how electorialism works in the real world, both in the past and the present, and thanks to that we live in an absolute utopia.

But on a more serious note, liberal democracy is just an illusion of freedom and an illusion of “power for the people”. In reality, it’s been meticulously crafted to only benefit the rich with its barriers for entry designed to keep the poor out - for instance, one has to get an expensive education to even get started (or have a load of money to buy a degree outright), having enough money to fund a platform for yourself to get enough supporters to form a party, then do expensive advertising of your party’s message, having funds to combat any kind of political meddling from the competition, connections that one wealthy enough might get are also incredibly helpful, etc. There’s a reason why the vast majority of politicians parents links are blue on wikipedia - it’s not a meritocracy.

There’s many more critiques like how checks & balances are there to keep the capitalist system and not necessarily to stop abuses as certain populists are demonstrating nowadays, how people are essentially powerless after voting for the next 4-5 years, electorialism being used to distract from class struggle (via reactionary politics, culture wars) which keeps people from turning against the rich properly and instead choosing which side of the rich one wants to support, etc.

In short, if there’s going to be any meaningful, good change for us workers, it isn’t going to come from electorialism, and its important to be aware of this fact, not grow too complacent.

At the same time, there’s no revolution to be seen, partly precisely because of the things outlined above so yeah…
