Absolutely, but those things are a drop in the bucket relatively speaking and aren't systemic budget problems. By far the biggest culprits are Medicare/Medicaid and the Bush tax cuts, but neither party has the collective will to do anything about them. It's not totally their fault, either- it's the nature of the political system and the level of voter awareness. Anyone who started seriously gunning for any of those things would get voted out at the earliest opportunity, or at least that's their perception. It's a profoundly messed up situation.
