"It's also why I am extremely unpersuaded by the prevailing media narrative that the Right is suddenly enthralled to its rambunctions and extremist elements and is treating Obama in some sort of unique or unprecedented way. Other than the fact that Obama's race intensifies the hatred in some precincts, nothing that the Right is doing now is new. This is who they are and what they do - and that's been true for many years, for decades. Even the allegedly 'unprecedented' behavior at Obama's speech isn't really unprecedented; although nobody yelled 'you lie,' Republicans routinely booed and heckled Clinton when he spoke to Congress because they didn't think he was legitimately the President (only for Ted Koppel to claim that it was something 'no one at this table has ever heard before' when Democrats, in 2005, booed Bush's Social Security privatization proposal during a speech to Congress).
"This is why so many people were so skeptical of the heartfelt belief among many Obama supporters that he was going to usher in some sort of new, harmonious 'post-partisan' age. The long-standing and well-established nature of the American Right would never permit such a transformation."
