I wonder what he’s thinking. It is possible, of course, that he considers Hagel-Martinez genuinely much better than the Judiciary Committee bill. Or perhaps he thinks that he made a mistake in taking the enforcement-first line, having gotten so much bad press coverage (and presumably corporate pressure) as a result of it. But it’s hard to see anything that feinting first this way and then that has done for him politically. Which brings up another possibility: He has no idea what he’s doing.
