President Bush's paramount problem with his National Guard years is not that he took shortcuts in 1972. The problem is that he still refuses to come clean about it.

There's no doubt that Mr. Bush benefited from favoritism. The speaker of the Texas House has acknowledged making the call to get Mr. Bush into the National Guard.

Does any of this matter? What troubles me is less Mr. Bush's advantage three decades ago and more his denial today. Mr. Bush's own route to avoid the draft underscores the disparities in America, yet his policies seem based on a kind of social Darwinism in which the successful make their own opportunities. His tax cuts and entire outlook seem rooted in ideas not of noblesse oblige, but of noblesse entitlement.

The pilots I interviewed who were in Alabama then are pretty sure that Mr. Bush was a no-show at required drills.

The next year Mr. Bush skipped off to Harvard Business School. He still had almost another year in the Guard he had promised to serve, but he drifted away, after taxpayers had spent $1 million training him, and he never entirely fulfilled his obligations.
