The first few chapters are pretty dense and Posner writes unnecassarily complicated sentences. He begins by writing how so many people talk about democracy; that this is good for democracy or that is good for democracy, but no one ever defines democracy when talking about it or are inconsistent. He essentially breaks it down to two, rather broad concepts: creatively called Concept I and Concept II.
Concept I democrats, Posner claims, regard democracy in a purely abstract sense- rule of the people, by the people, for the people, with some severe and very undemocratic ideas of governance. For example, there are many things that should be legal or illegal, no matter how for or against something the general public is. Also, Concept I democrats have an unwarranted confidence in the knowledge and disinterestedness of public officials, especially, those not democratically elected (judges, for example). The most defining characteristic of Concept I democrats is the their utopian leanings, meaning they strive for a perfect society and government- that principles should be clung tightly too, regardless of the outcome.
Concept II democrats have no such illusions and accept American democracy and the people in it as they are. As such, they accept, and encourage, many things Concept I democrats find evil. For example, the fifth amendment, taken to its logical conclusion, means that no one could be forced to be finger-printed, or to give a blood sample. However, this would make law enforcement and prosecution too hard, so these things have been ruled as not in violation of the fifth amendment. Posner gives many other examples. Basically, Concept II democrats hold democratic principles dearly, but are realistic about applying these principles in real world situations.
The last couple of chapters held my interest the most. Here Posner focuses on two cases, Clinton v. Jones, and Gore v. Bush. He focuses more on Gore v. Bush. He thinks the ruling of Clinton v. Jones was unpragmatic, that the case should have waited till Clinton's presidency ended because of the very real possibility that the case would be too distracting for Clinton to effectively run the government.
He thinks the ruling in Gore v. Bush to be an excellent example of pragmatic adjudication. Since the election was so close, it didn't matter which candidate became president, in terms of democracy. Since, at the time of the ruling, Bush had more votes, he became president. He regards the putting off of the smooth succession of the president, possibly beyond Jan. 21, in the name of "every vote counts" to endanger society. He claims a smooth succession of the president is more important than taking the time to count every vote, creating very serious problems in the interum.
