We can’t — shouldn’t — blame Sarah Palin for what happened in Tucson … but it was/is shocking to revisit her political advertisement from last year — with Representative Giffords’ state of Arizona in the crosshairs. And I do know this — if the advertisement — and Palin’s rhetoric of “lock and load” had been done and said by someone like Marilyn Manson, there wouldn’t be a doubt in anyone’s mind about drawing a parallel.

This is all just a sad, sad mess.
