Hmm, i think it's great they have a written constitution and everybody is aware of it. That's one of the factors which led to Chavez being repositioned in power after the attempted revolution (apparently initiated by american forces?).
On the other hand, Venezuela has a recall function where, if a certain number of people want to throw out someone from government, they collect a certain number of signatures. Apparently, the opposition party collected enough signatures to throw Chavez out but he didn't accept it. Surely, a fair and democratic leader would either step down or change the law if he didn't think it was valid
Later on they found out the opposition party had included the signatures of people who had died a year ago, but that didn't come to light until after he refused to step down.
I don't know much about Venezuela but it seems to have a very interesting political system.
