:::How about if we give it some more time, continuing to try to educate them about policy via the talk page?  It's better to educate new editors than to alienate them, and they probably just don't understand that they can't delete sourced text and insert improperly attributed statements.  (There are now three of them, and there will be more.)  A word to the wise from admins to help steer them may help, but I think it's early for semi-protection (which will certainly be needed eventually, as this appears headed for a heated one, as happened with Lieberman in the primaries).
