The Kaiser Family Foundation has been conducting a longitudinal panel survey on the uninsured in California. The organization focused on that state because California has had such a large portion of the nation's uninsured, and its experience has national implications. As does the finding that, thanks to California's success with Obamacare, there are 3.4 million fewer uninsured people now. Of those Californians who were uninsured prior to open enrollment, 58 percent now report having health insurance, which translates to about 3.4 million previously uninsured adult Californians who have gained coverage, and 42 percent say they remain uninsured.1 The most common source of coverage was Medi-Cal with 25 percent of previously uninsured Californians reporting they are now covered by Medi-Cal.
