The thing about picking the lesser evil is that it’s supposed to make the sides compete against one another. It doesn’t take a single election to change the atmosphere of politics. It takes many iterations to make the politicians understand what the people want, if the only communication from the people is via voting.

That’s why you pick the lesser evil, because the only way they would otherwise make things worse is by joining up and working together to destroy the country and its people. But then you have bigger issues than democracy.
