Am I Now, or Have I Ever Been, a Deficit Hawk?
In a word, yes, but Stan's thoughtful post prompted me to think again about what it means to be a deficit hawk. With some further reflection, I think there are two incentive problems that dominate all others on domestic policy.
One of these problems is that the federal deficit serves as a mechanism to facilitate the use of future taxpayers' income to buy votes for elected officials today.* To be a deficit hawk is to be vigilant against all possible instances where that may occur. Our political system creates many opportunities for it. I think my best statement on the problem was How to Advise on Fiscal Policy, posted in July 2007. Here is the key excerpt, pertaining to what the President's advisers should be doing about it:
On fiscal policy, the three main advisers are the Secretary of the Treasury, the Director of the Office of Management and Budget, and the Chairman of the Council of Economic Advisers.
Deficit hawks, whether in government or not, should be relentless in pressing for policies that accomplish these ends.
*The second problem is that the buying of policy outcomes by organized interests to the detriment of the general population is rampant, bipartisan, and disgusting. Until I heard it explained to me by an expert, I did not realize how necessary it is to reform the way elected officials and candidates for elected office raise money. It is not the lobbying -- the petitioning of the government -- to which I object. I object to the flow of money from groups to politicians. As I noted here, I would prefer a system in which it would not be legal to give money to a politician who would not represent you as a constituent. Given legislative history and Supreme Court rulings, this would be a major battle. As it pertains to the topic of the post, this problem may compound the first -- organized groups may press their special interests at the expense of the general welfare of people alive in the future as well as those alive today.

Great idea re: restricting campaign contributions to candidates of whom one would be a constituent.
Earlier today I offered my thoughts re: mitigating the adverse and unfair influence of money on policy at http://capitalgainsandgames.com/blog/stan-collender/1332/breaking-defici... I'd be interested in your thoughts.
Theory versus Implementation
Everyone agrees that entitlements are growing out of control. We've been hearing about it for years. Not that it doesn't bear repeating, but it seems like the main trouble seems to be not in determining what we need to do, but in actually implementing it. It's been politically impossible to wrest away benefits from those getting the benefits. As you mentioned, the incentives for any elected official are to pass the buck.
In other words, all right, it's hazardous and unjust to spend beyond our means with no foreseeable way to pay back our debtors. Granted. But how do we reverse the direction of the train barreling down the tracks in the wrong direction when the controls to the system are in the hands of the beneficiaries of the systems' brokenness?
