In the last post I said I might comment more on this, when I had more information and some perspective. But I will say that I think it looked a bit absurd for Ron Paul to say to Wolf Blitzer (part I and part II) that he had no idea who wrote those things. I am fully prepared to believe that he didn't write them himself; after all, it's not even his style. But that's all the more reason that he should have been really upset when it was brought to his attention, and at that point he certainly should've found out who was responsible.
Incidentally, I am glad Paul didn't name names. I think that would've appeared that he was trying to make a subordinate fall on the sword for his own (Paul's) political prospects. It's just that I think instead of saying he didn't know who wrote it--which makes it sound like either an obvious lie or that he really wasn't so bothered by those newsletters in the first place--he could've said something like this:
You know Wolf, this stuff is over a decade old. Yes, at the time of course I figured out who was writing this stuff, since I didn't agree with it and it was going out under my name. But I'm the one running for president; there would be no point in me subjecting someone else to these attacks. I take responsibility for what happened, it was an oversight on my part, but this is ancient history. My supporters know that I am the champion of the individual and abhor racism and all forms of collectivism. Let's please move on and discuss the real threats that black Americans and other minorities face today. Believe me Wolf, they're not endangered by my newsletters from 20 years ago!
