I believe that that democratic government has a stable outline, but is often thought of as weak because of people disliking elected officials and the vastness of opinion and belief. This can lead to it to be semi-religious or force opinions by passing laws. otherwise, they are pretty stable, with house of rep. giving even smallest of opinions a voice, a Judaical branch that deals with issues between peoples, and people all over keeping citizens safe. (of course there's always going to be a crooked person, but that's why there are branches, making sure no one has utmost power.)
