Professor William Jacobson at his Legal Insurrection blog does a fine take down of the so-called "Buckley Rule" that political pundits like Charles Krauthammer and the Powerline guys have lately been invoking as justification for being against Tea Party backed/conservative candidates like Christine O'Donnell.
In short, Jacobson refutes the underlying assumption that the late William F. Buckley ever intended to make a generally applicable political rule that Republicans should always support the most politically conservative candidate who has the best chance of winning. Such a rule would have been untenable for Buckley since it effectively results in what Jacobson describes as a "tyranny of the establishment."
Having thoroughly dispelled the notion that a "Buckley Rule" exists and is wise, Jacobson goes on to give the normally reasonable Krauthammer, and those who would agree with him, some sound advice:
Make your case for a particular candidate in a particular race. But don't invoke some illusory "Rule" just because you don't like the outcome.Update: In their commitment to unity in the Republican Party, Powerline perpetuates and gives legitimacy to a typically idiotic Bill Maher troll. Nice going guys - not!
