California residents are rebelling a bit against Obamacare, with thousands shocked by the sticker price and rethinking their support, saying that what seemed wonderful in principle is not translating so well into reality.

As Pam Kehaly, the president of Anthem Blue Cross in California, reported, she received a letter from one woman who saw her insurance rates rise by 50 percent due to Obamacare.

“She said, ‘I was all for Obamacare until I found out I was paying for it,’ ” Ms. Kehaly said, in the Los Angeles Times.

Several hundred thousand other Californians in coming weeks may be feeling the same pinch, as insurers drop their plans and push them onto exchanges, medical analysts say. Blue Shield of California sent letters to 119,000 residents last month announcing the plans don’t meet federal mandates.
