We know what to expect from an Autocrat, but what can we expect from a democrat?

We know what to expect from an Autocratic government, but can we know what to expect from a democratic government. Obviously, forms of government that emphasize autocracy are predictable. But, such is not the case with a democratic form of government. True, a democracy has to be a form of government "of the People", "by the People" and "for the People". But, its not that simple. Many variables enter the democratic picture. Some Parties favor and protect the economy and corporations, and some Parties favor and protect the People at the Bottom. The problematic is that the ascendancy to power is relatively simple, but once someone assumes the position of power, the carrying out of policy and law is not always democratic. For example, declaring war against another Country and justifying that move by saying we are "bringing them democracy"(no references to killing civilians, women and children). Sounds ridiculous, yet that has occurred before. Or, how about justifying a Court decision, by deciding that a corporation (a legal fiction) has a Constitutional Right to 'freedom of speech', just like a 'real' human being. Corporations are recognized "legal fictions" and hence are not 'real', in the same sense as 'real' human beings, and hence should not be allowed to 'participate' in the political process. The founders and the individuals behind the corporate façade are 'real' and they can always participate in politics. But, why grant a right to an artificial 'person' that only exists "in contemplation of law". The only way to keep a democracy, democratic, is for the people at the Bottom of government to always be on their guard. Maybe we could have a law that says if a politician promises something, s/he should be held to that promise. We require that in contractual obligations. We should not allow frivolous campaigning and false advertising in political campaigns. The People deserve better. The right to ascend to a position of power should be monitored more closely. Democracy should also be protected.
