Chart: Another Republican litmus test

In a new survey from Public Policy Polling, two-thirds of Republican primary voters say they wouldn't vote for anyone who supported the individual mandate in federal health reform. This can't be great news for Jon Huntsman, who backed an individual mandate in Utah, and who comes in at 2 percent. But Mitt Romney, who put an individual mandate at the heart of health reform in Massachusetts, comes in second at 20 percent.
