Technically, I don’t think bankruptcy is even possible since there’s no provision for such a step in federal law.
But it’s still an interesting issue, so I decided to create a poll on the question. To make it manageable, I limited the selection to 10 states, all of which rank poorly in one of more of the surveys listed above. And, to avoid technical quibbles, the question is about “fiscal collapse” rather than bankruptcy, default, or bailouts. Anyhow, as they say in Chicago, vote early and vote often.
