David Boaz at Cato blogs on the newsletters controversy:
Assuming Ron Paul in fact did not write those letters, people close to him did. His associates conceived, wrote, edited, and mailed those words. His closest associates over many years know who created those publications. If they truly admire Ron Paul, if they think he is being unfairly tarnished with words he did not write, they should come forward, take responsibility for their words, and explain how they kept Ron Paul in the dark for years about the words that appeared every month in newsletters with “Ron Paul” in the title.
That’s the heart of the matter.
UPDATE: In fairness, I should add that based on Kirchick’s piece, the ugly racist stuff all appears to fall between 1988 and 1992 (don’t forget either that Paul was running for president in 1988). It can’t be impossible to figure out who was writing the newsletter during that period.
