Please take a look at:
http://www.wikipedia.org/w/ wiki.phtml?title=Joseph_McCarthy&diff=895253&oldid=894480
(the URL may need to be pasted together). This edit, marked as *minor*, is the work of one "Moses ben Nachman", a Wikipedia user with a very brief edit history who just announced on his talk page that, "after several months, I have decided to give this internet project another chance."
I strongly suspect that "Moses" is really the banned user Clutch. The above edit is exactly his style (like changing "heavy drinking" to "social drinking"), and even includes a link to a text on Clutch's homepage ("How the Marxists destroyed Joe McCarthy"), reactor-core.org. Moreover, if you check his user page, you will find that he was immediately welcomed by Clutch -- and then complained about RK, as Clutch also did. In the McCarthy edit, he removed large slabs of text without explanation.
I'm not involved in the McCarthy article, but I suggest people keep an eye on it, and on "Moses'" other edits. Yes, the McCarthy article was slightly POV before the edits, but I doubt that it will be possible to make it NPOV with the "help" of someone like "Moses".
