Colorado Gov. John Hickenlooper was a restaurateur before becoming Denver's mayor, a career that taught him valuable lessons about service that stand him in good stead as a public official, he told about 300 attendees at a gathering of NRA's Marketing Executives Group. Hickenlooper urged the group to consider spending at least part of their careers in public service. "If you really don't like the Affordable Care Act, one cause of that is because the people who wrote it -- lobbyists and legislators -- hadn't been in business. ... If they had been in business, we'd have had 100 times better legislation," he said.
