From 3/13/08:

When Senator Barack Obama was kind enough to respond to our request for a hands-off policy toward other Democrats, he was quick to remind us that pointing out differences isn't the same as attacking. Wouldn't it be great if everyone in the Obama camp grasped this concept? Of course, strongly in his favor is the fact that, at least Senators Obama and Edwards, and Democratic Chairman Howard Dean responded. I haven't heard word one from Senator Clinton. So, as always, it's a mixed bag. You've got to credit the Senator, and his campaign, for being attentive and responsive to different points of view. But you've also got to wonder what all the griping is about.
