(WASHINGTONPOST) — The landmark health-reform law passed in 2010 has never been very popular and always highly partisan, but a new Washington Post-ABC News poll finds that a group of once loyal Democrats has been steadily turning against Obamacare: Democrats who are ideologically moderate or conservative.

Just after the law was passed in 2010, fully 74 percent of moderate and conservative Democrats supported the federal law making changes to the health-care system. But just 46 percent express support in the new poll, down 11 points in the past year.

Liberal Democrats, by contrast, have continued to support the law at very high levels – 78 percent in the latest survey. Among the public at large, 42 percent support and 49 percent oppose the law, retreating from an even split at 47 percent apiece last July.
