Katrina vandenHeuvel @KatrinaNation Alexander Cockburn,longtime Nation columnist, radical journalist, unwavering voice of dissent,RIP, 1941-2012. So I’m laying in bed checking Twitter, and the above comes across. I didn’t know Mr. Cockburn, and I wish his family the best in their time of healing. But what struck me about this is the “unwavering voice of dissent” part. I think this is what gets liberals off on the wrong track a lot.
