This blog item was posted over the weekend, but it's worth a read in the wake of Sarah Palin's defense of vigorous public debate and free speech today.

From Obama London, a blog maintained by expat supporters of the president:

Sarah Palin has a reputation for being an agressive editor of comments on her Facebook page - a reputation that has always seemed likely accurate to me, given the tedious consistency with which all comments on the page are along the lines of "I love you SARAH!"

But in the wake of the terrible events in Arizona, with many commentators pointing out the obvious fact that Gabrielle Giffords had been targetted by Palin in the November election on a map that used a chilling gun site graphic, I thought it would be worth watching her page for a little while to see if her team were indeed deleting negative comments routinely. But I had no idea how incredibly, almost comically, efficient her people would turn out to be in deleting comments that were even slightly critical of the former Governor. And then I came across... well, what I guess you'd have to politely call an appalling example of editorial misjudgement at best.
