Most states require that you carry ID also, but an ID cannot be denied to you, even if you are a convicted felon. A passport, on the other hand, will become the preferred method of restricting travel. All the more reason the US is motivated to pump out as many felons as possible. If they can't lock them all up in their fancy private prisons, the lack of a passport will damn near put them under house arrest as the next best thing. The government acting this way doesn't bother me nearly as much as the public's acquiescence. Resistance is feeble to nonexistent.
