"There are always some whose aspirations to rule will be satisfied. In keeping with Friedrich Hayek's analysis, it is overwhelmingly more likely than not that they will be the most ruthless and least scrupled of all the forces of darkness. In a struggle over political power, those are advantages.
Very seldom have political upheavals not elevated the very worst to the very highest positions. Moreover, the "very worst" are aware of this, which is why one finds a disproportionate number of the unscrupulous -- the liars, the thugs, the embezzlers, and miscellaneous other blackguards -- in the strategy councils of left-oriented movements. Search as long as you like; you will never find anyone resembling Saul Alinsky among conservative or libertarian thinkers. Such a person would rebel against the promotion of individual liberty; he'd seek to undermine it at every opportunity, such that no one on the Right would listen to him.
No, it's on the Left that you'll find the Rahm Emanuels and the David Axelrods, the Jeremiah Wrights and the Al Sharptons, the Tony Rezkos, the Rod Blagojeviches, the Alex Giannoulias, the Bill Ayerses and Bernardine Dohrns."
Most of those individuals are merely clever, such as The Voice Of The Teleprompter, little Barry Soetero/aka Barack Hussein Obama/aka Frank Marshall Davis, Jr.Obama's ability to move crowds with his voice - similar to the ability of a certain German politician back in the early 1930's - is proven to be simple oratory and not intelligence, when you take away his teleprompter. (Or if you input nonsense into his teleprompter. But his speech writers are not much brighter than he is, evidently.)
