What If Romney Loses Michigan?

When asked about possibly losing Michigan to Santorum, Romney replied, "That won't happen." Chait is puzzled by Romney's certainty:

With the proper spin, Romney could persuasively portray a split decision, where he wins Arizona and loses Michigan, as a big win. (It would be, delegate-wise.) Instead, he’s made the Arizona race almost completely invisible, and positioned his campaign to suffer a narrative of collapse if Santorum can maintain his lead in Michigan. Now, Romney stands a strong chance of catching Santorum by employing his familiar method of overwhelming financial superiority. But, hey, maybe Santorum can hang on. Why has Romney decided to make the state do-or-die?

 Because it is increasingly clear he is an awful politician.
