I don't know if it will be better or worse off compared to today...but I do think that it will be GETTING better by then. Any deterioration that might occur will be mostly front-loaded: I suspect that we'll have a few more years of high deficits (still dealing with the aftermath of the recession), but we'll manage to tackle at least 2 of our 4 long-term deficit drivers (social security, defense, health care, tax policy). By 2015, I suspect that our debt-to-GDP ratio will be falling.
I think there is plenty of opportunity for deficit reduction via defense spending and tax revenue, specifically. Social security is a bit tougher to tackle politically, but since all of our long-term SS problems can be solved with some relatively minor tweaks, I hold out hope that an agreement can be reached on this issue as well. Health care is the only one that really seems intractable at this point in time, but there may be more opportunity to tackle that as well once the Affordable Care Act is fully implemented and passions around it die down.
