The U.S. administration on Monday dramatically cut expectations for 2015 Obamacare enrollment, saying it aims to have a total of 9.1 million people enrolled in government-backed federal and state health insurance marketplaces next year. The stated goal, 30 percent lower than a Congressional Budget Office forecast of 13 million enrollees, reflects the government's latest thinking about new enrollees and returning customers, according to officials who expect the actual number to fall between 9 million and 9.9 million.
