It is mostly the same parties sitting in government as back in Weimar when they helped Hitler ban the biggest competition. I am quite sure some of them even date back to our last Kaiser (not the soccer one). What is a single person to do against political parties that historically should be considered complicit in starting and losing two World Wars and survived without having their ideologies purged?

To an extent, yes, but I believe real-life has shown that removing incumbents is very difficult. I sense that the makeup of the district and the composition of party strength is the major factor in determining whether or not a politician is reelected or replaced, rather than popularity or approval rating.
