It has already been reported here, here, here, here and here, but I have a few final comments.
It's a good sign for the Cox campaign that this was quickly nipped in the bud. This type of "scandal" is the perfect blog fodder. A quick reaction to squelch this type of misstep speaks to a well organized campaign machine.
The sad fact is that I believe this latest Wikismear is only the tip of the iceberg. As one of my commentors pointed out, Wikipedia has already been forced to shut off all editing from Capitol Hill domains. Now, it is apparent this hideous tactic is filtering down to the state level.
It should be stopped. If political operatives manage to ruin the reputation of an internet resource the stature of Wikipedia, how does anyone deny what most of the public already believes? That politics is poison.
