The blogger Emptywheel documents the very bipartisan concern over the McCain camp's hatemongering and while Howard Kurtz asks on CNN "Why are the media this week pumping up this story about McCain and Palin's crowds as if it is their fault if there's a bit of ugliness that breaks out?" A guest of his answered:

"When your vice presidential running mate goes around the country saying Barack Obama is palling around with terrorists, and when you run ads that say, you know, he's a liar, he's not telling the truth about this unrepentant terrorist, and then you wonder why people in the crowd shout out 'terrorist' when you mention the name Barack Obama, this anger is coming from somewhere. It is being ginned up by a campaign, and it is logical, I think, to assume that these people are only responding to what they have heard from the candidate's mouth. And it's fair game and it's, in fact, responsible for us to report how the crowds are reacting."

...just released this excellent new video, which features some of this footage that Morrill got:
