At a rally late today in Minnesota, John McCain addressed the heated comments, including calls to violence, coming from some supporters at his rallies this week:

"I am enthusiastic and encouraged by the enthusiasm and I think it's really good," McCain said. "We have to fight and i will fight but we will be respectful. I admire Sen. Obama and his accomplishments and I want to be respectful.

Here's the (updated longer version) video of a portion of McCain's remarks:

Late Update: Ana Marie Cox is on the ground at the rally and reports:

Indeed, [McCain] just snatched the microphone out the hands of a woman who began her question with, "I'm scared of Barack Obama... he's an Arab terrorist..."

"No, no ma'am," he interrupted. "He's a decent family man with whom I happen to have some disagreements."

Later Update: In the expanded version of the video above, I don't hear any reference to terrorist when the woman calls Obama an Arab.
