David Walker, the former comptroller general who has tried to draw attention to the debt and entitlement problems, has endorsed Mitt Romney for president. “He has stated a commitment to fiscal responsibility and true government transformation. I was personally reassured by a meeting with him covering his commitment and approach to tax, defense and several other key fiscal issues.”

So Romney “state[s] a commitment to fiscal responsibility” — even Walker can’t actually believe his silliness about “true government transformation,” whatever that’s even supposed to mean — and tells Walker he’ll do a good job. Walker then endorses him on the basis of these empty assurances, which run counter to Romney’s stated views and — putting it mildly — lack of urgency on the debt question. An unflappable man of principle, this Walker.
