The January Kaiser Health tracking poll, conducted jointly with the Harvard School of Public Health, now shows Obamacare to be less popular than at any time since its passage. For the first time since Obamacare became law, Kaiser now shows 50 percent of respondents holding an “unfavorable” opinion of it (up from a previous high of 45 percent in this poll), with only 41 percent holding a “favorable” opinion of it. The Kaiser Health tracking poll has always been an outlier poll, showing unusually favorable results for Obamacare. Previously, the largest margin of opposition in this poll was just 3 points, compared with this month’s 9-point margin of opposition.
