After a three-month stint in federal prison for political dirty tricks, Allen Raymond has written a tell-all book about his 10 years as a Republican political consultant: “How to Rig an Election: Confessions of a Republican Operative.” A specialist in “robo-calls” used by campaigns, Raymond hired a firm to make endless calls to a Democratic phone bank to prevent outgoing calls urging voters to head to the polls in the 2002 New Hampshire Senate election. The 42-year-old Bethesda claimed he was acting at the behest of another operative who was later convicted of similar charges. That conviction was later overturned on appeal. He spoke with The Examiner about how his mistakes changed him, and the ethics that guide him.
