WASHINGTON — What’s generally termed ObamaCare wasn’t the brainstorm of President Obama, but an Alice in Wonderland “witches brew” concocted in 2010 by Senate Majority Leader Harry Reid and then House Speaker Nancy Pelosi with generous advice from Big Pharma, Big Insurance and the AARP. All three groups stood to make billions off a convoluted bill that added 19 million potential new customers to the nation’s health-care system, but hardly anyone in the Democratic majorities that rammed the bill through Congress had any idea what the legislation actually contained. As Pelosi famously said on March 9, 2010, “We have to pass the bill so that you can find out what is in it.” Now Democrats are finding out key sections of the law may contain the seeds of its own destruction.
