> What I'd really like to know is what process does the President-elect endure that turns him into an alien lizard from hell?

A Truman-era bureaucrat coined the phrase, "where you stand depends on where you sit."

When Obama was outside the executive branch and had only a year of Senate experience before embarking upon his presidential campaign, he had a very different set of interests and responsibilities. As a junior, back-benching senator with no Washington DC experience, Obama had very few capabilities or political capital. People who are weak decry the power of the strong and seek to limit it.

When Obama became president and was given responsibility not just for Illinois, but for the United States and its allies, he assumed a very different set of responsibilities, interests, and capabilities. Obama entered office with a tremendous amount of political capital and the full panoply of executive branch powers at his disposal. The powerful do not generally seek to limit their own power or to accept limits placed upon them.

This happens to every candidate-turned-president, but with some it's more extreme than others. Some presidents enter office with executive branch experience, e.g. Bush Sr. or Eisenhower. Some enter with tremendous political capital and experience with DC politics, like LBJ a.k.a. the "master of the Senate." The transformation is not so great with these presidents.

Some enter with almost no political experience whatsoever, like Obama. The subsequent transformation is much more jarring, because the change in their power is much starker.

> I mean, seriously .. its like black and white with Obama. Pre-Presidentiality, Obama was real. After-President'ness, he's become some obscure caricature of all other Presidents who came before him..

On the contrary, pre-presidential Obama was fake. He was in campaign mode from his entrance on the national scene in 2004 through 2008. You cannot honestly believe that the campaign image of a politician is the "real" version of that person.

Presidential Obama is the real Obama. Abraham Lincoln said, "Nearly all men can stand adversity, but if you want to test a man's character, give him power." This is who Obama is. There's a reason why presidents seem to feature greater continuity than change, and part of that reason is that the responsibilities of the office don't change according to the president, rather the president must change in order to perform the responsibilities of the office. Many wildly different personalities can occupy the office, but the office structures and constrains those personalities.

Idealists often have a consequence-free vision of what presidents ought to do (a "deontological" ethic). But politics does not work that way. Max Weber contrasted the (deontological) "ethic of ultimate ends" with the "ethic of responsibility" in his essay "Politics as a Vocation," which I urge you to read. http://www.sscnet.ucla.edu/polisci/ethos/Weber-vocation.pdf

Responsibility is a different ethical standard than what individuals on their own would be held to. And what an individual ought to do is very often different from what someone responsible for the lives of others ought to do. And the actions a responsible political figure ought to undertake are often morally repugnant to the private individual. But it is a mistake to judge the leader by the standards one would use to judge a private citizen. Weber says as much:

> "It follows that as far as a person's actions are concerned, it is not true that nothing but good comes from good and nothing but evil from evil, but rather quite frequently the opposite is the case. Anyone who does not realize this is in fact a mere child in political matters."

Isaiah Berlin in his famous article on Machiavelli (http://www.nybooks.com/articles/archives/1971/nov/04/a-speci...) puts it even more starkly:

> If you object to the political methods recommended because they seem to you morally detestable, if you refuse to embark upon them because they are, to use Ritter’s word, “erschreckend,” too frightening, Machiavelli has no answer, no argument. In that case you are perfectly entitled to lead a morally good life, be a private citizen (or a monk), seek some corner of your own. But, in that event, you must not make yourself responsible for the lives of others or expect good fortune; in a material sense you must expect to be ignored or destroyed.

> To be a physician is to be a professional, ready to burn, to cauterize, to amputate; if that is what the disease requires, then to stop halfway because of personal qualms, or some rule unrelated to your art and its technique, is a sign of muddle and weakness, and will always give you the worst of both worlds. And there are at least two worlds: each of them has much, indeed everything, to be said for it; but they are two and not one. One must learn to choose between them and, having chosen, not look back.

> There is more than one world, and more than one set of virtues: confusion between them is disastrous. One of the chief illusions caused by ignoring this is the Platonic-Hebraic-Christian view that virtuous rulers create virtuous men. This, according to Machiavelli, is not true. Generosity is a virtue, but not in princes. A generous prince will ruin the citizens by taxing them too heavily, a mean prince (and Machiavelli does not say that meanness is a good quality in private men) will save the purses of the citizens and so add to public welfare. A kind ruler—and kindness is a virtue—may let intriguers and stronger characters dominate him, and so cause chaos and corruption.
