Alito's Personal Statement:
The statement of his political views that Sam Alito made as part of his application to become a political deputy at the Office of Legal Counsel in 1985 is available here, on pages 15-16. The document was written in response to the following question:
  Have you ever served on a political committee or been identified in a public way with a particular political organization, candidate, or issue? (Please be specific . . . )

  UPDATE: A reader points out that I may be misreading the form, and that the Alito essay is probably a response to this somewhat different question:
  Please provide any information that you regard as pertinent to your philosophical commitment to the policies of this administration, or would show that you are qualified to effectively fill a position involved in the development, advocacy and vigorous implementation of those policies.
