"As a tool for understanding the thinking of Obama, [Saul] Alinsky's most famous book, Rules for Radicals, is simultaneously edifying and worrisome. Some passages make Machiavelli's Prince read like a Sesame Street picture book on manners. After Obama took office, the pundit class found itself debating the ideology and sensibility of the new president --
an indication of how scarcely the media had bothered to examine him beforehand. But after 100 days, few observers can say that Obama hasn't surprised them with at least one call. ...
Obama is a pragmatist, but a pragmatist as understood by Alinsky: One who applies pragmatism to achieving and keeping power. ...
Moderates thought they were electing a moderate; liberals thought they were electing a liberal. Both camps were wrong. Ideology does not have the final say in Obama's decision-making; an Alinskyite's core principle is to take any action that expands his power and to avoid any action that risks his power. As conservatives size up their new foe, they ought to remember: It's not about liberalism. It's about power. Obama will jettison anything that costs him power, and do anything that enhances it.... It's not about the policies or the politics, and it's certainly not about the principles. It's about power, and it has been for a long time."

My only disagreement with above is that I still think his core beliefs are radical socialist .
