I understand this, that's why I didn't go to the elections. Since I once had a government job, one of the conditions for continuing my contract was "go and vote," but I didn't do it, because it's impossible to check.
But you know what? Nobody cares.
The government will rig the election results, and no one will stop them from doing it. I'm not saying that we should throw up our hands and calm down now. But the problem is that the system is already well-established and well-coordinated. And our place in it, unfortunately, is predetermined, while our opinion doesn't really matter to anyone.
I understand why you are frustrated with election system. It feels like your vote do not count and that outcome already decided. It is especially disheartening when we think government may manipulate election results. I do not have much knowledge about other countries but I know about my country and here establishment change everything and they have power and they decide that who will be the winner. Therefore many people don't trust on election system. By the way keep in mind that when people work together and persist they can create change even if it seems small at first.
