That’s all democracy ever is. A check to keep the worst people from being in power. Non-democracies don’t have this, you have to use violence to remove bad people from power. And most likely die trying to do it.
They really should tech in schools how voting really works. Figure out who the worst one is, and vote for the one that is most likely to beat the worst one. You never get everything you want in one election cycle, you have to keep on voting again and again and over a few decades you get some progress. It sucks but it’s better than the alternatives.
That’s why voting is a duty, it sucks, but you have to do it.
