It's Stephen Colbert's world - we just live in it
Most people seem amused by the notion of a comedian entering the race for president, though most also seem to feel that he cannot possibly harm the dignity and sanctity of the process since it is already trailing along in the mud, on various levels. However what makes Colbert a dangerous candidate is the same thing that makes him a dangerous talk-show host: his utter lack of hypocrisy. He embraces the absurd, takes the most alarming doctrines of the right and pursues them to their 'logical' conclusions. Where most public figures gloss over inconsistencies in their positions or unpopular issues, Colbert charges forth, ostensibly blind to all but the beautiful music of his own drummer.
The Colbert Report is first-class satire in the truest sense of the term (as opposed to the amusing, but less trenchant parodies of The Daily Show) and it is a treat to see the man himself enter an already surreal ring at the peak of his powers. Whatever happens in South Carolina, it is sure to be interesting.
