We Do Not Understand What the Hell Mike Gravel Is Talking AboutThe star of last week’s Democratic presidential debate was a fringe contender Mike Gravel, 77, a former Alaska senator, who became a blogosphere sensation for saying that it should be a felony for Dubya & Co. to stay in Iraq. (He also drew laughs when he said the leading candidates scare him because they won’t rule out bombing Iran. “Who are we planning to nuke?” he asked Barack Obama. “I’m not planning to nuke anybody right now, Mike,” responded the Illinois senator.) Gravel — it’s pronounced gra-VELL — is a Columbia alum who drove a New York City cab while a student, and he’s back in town for appearances on The Colbert Report tonight and the Today show tomorrow morning. We spoke to him before he left his Virginia apartment, which doubles as his campaign headquarters — and we hope Colbert’s interview goes better than ours did.
