The GOP has gleefully jumped on media reports about Americans having their health insurance plans nixed because of Obamacare. "Obama lied. My health plan died," conservative blogger Michelle Malkin wrote in September, referring to President Barack Obama's promise that people who liked their health insurance plans could keep them. But how many Americans' health plans would receive some form of cancelation notice if GOP hard-liners got their wish and repealed Obamacare? Probably at least 150 million.
