Here's how Saletan summarizes his investigative report that you can read on-line:
"When you see the story in its full context, three things become clear. First, this was no flip-flop. Romney is a man with many facets, groping his way through a series of fluid positions on an array of difficult issues. His journey isn't complete. It never will be. Second, for Romney, abortion was never really a policy question. He didn't want to change the law. What he wanted to change was his identity. And third, the malleability of Romney's core is as much about his past as about his future. Again and again, he struggled to make sense not just of what he should do, but of who he has been. The problem with Romney isn't that he keeps changing his mind. The problem is that he keeps changing his story."
As I mentioned at the start , there can be no denial that he's been all over the lot on abortion. It's all on video and audio, folks. In his voice.
