As a presidential aspirant, Mr. Romney evidently hasn’t felt a need to be consistent or specific as to what should have been done to address the collapse of the auto industry starting in late 2008. But the gist is that the government should have stayed on the sidelines and allowed the companies to go through what he calls “managed bankruptcies,” financed by private capital.

That sounds like a wonderfully sensible approach — except that it’s utter fantasy. In late 2008 and early 2009, when G.M. and Chrysler had exhausted their liquidity, every scrap of private capital had fled to the sidelines.

I know this because the administration’s auto task force, for which I was the lead adviser, spoke diligently to all conceivable providers of funds, and not one had the slightest interest in financing those companies on any terms. If Mr. Romney disagrees, he should come forward with specific names of willing investors in place of empty rhetoric. I predict that he won’t be able to, because there aren’t any.

Without government financing — initiated by President George W. Bush in December 2008 — the two companies would not have been able to pursue Chapter 11 reorganization. Instead they would have been forced to cease production, close their doors and lay off virtually all workers once their coffers ran dry.

Those shutdowns would have reverberated through the entire auto sector, causing innumerable suppliers almost immediately to stop operating too.
