Ezra Klein posts the above chart from Kaiser and dares the GOP to overturn the popular parts of healthcare reform:
Everything from the subsidies to the increase in the Medicare tax is popular. The individual mandate isn't, and you might see the GOP focus on that, but tweaking the penalty there is a far cry from full repeal. Eventually, the GOP is going to stop being on the side of health-care repeal and find themselves on the side of allowing insurers to discriminate against the sick and seniors to fall into the doughnut hole, just as Democrats eventually found themselves on the side of the Cornhusker Kickback and $500 billion in Medicare cuts rather than health-care reform.
What will happen, David Frum predicts, is that the GOP will focus on the bill's unpopular elements but blink when it comes to repealing the legislation itself.
