A confidential training manual for Obamacare navigators that threatens prosecution for unauthorized dissemination is on the Internet for the world to see. The 217-page manual reads like a primer for Amway or novice car salesmen, offering sales advice on how to disarm potential customers who could be lured into purchasing insurance through exchanges created under the Affordable Care Act. Section headers include “Smile: Maintain a Positive Demeanor,” “Make the Customers Feel Welcome,” “Listen” and — in what must now seem ironic given Barack Obama’s troubles with over-promising — “Build Trust: Be True to Your Word.”
