Will Democrats stipulate that their Iraq withdrawal plans include defunding private contractors?

If we just replace American soldiers being shot at with more funding of private contractors,, i.e., mercenaries, then the war potentially becomes more burdensome on the budget, and not a whole lot easier morally, either. Read Mother Jones for some good reporting on what contractors are doing in Iraq right now, and on their belief that, if we pull out, the Iraq government will have to come calling on them. (Unanswered: Where will Iraq get the money to pay for these guys when [I hope] the U.S. gravy train pipeline gets shut down?)
