The IRS has announced it will postpone the start date of Obamacare’s “employer mandate” from 2014 to 2015. Most of the reaction has focused on how this move is an implicit acknowledgement that Obamacare is harmful, cannot work, and will prove a liability for Democrats going into the November 2014 elections.

Today, the nation’s top health economists released a study that throws a huge “STOP” sign in front of ObamaCare’s Medicaid expansion.

Florida Gov. Rick Scott (R) has decided to throw his support behind, or at least drop his opposition to, ObamaCare’s Medicaid expansion. His formal announcement is receiving much attention. Scott was an early opponent of ObamaCare. He parlayed that opposition into a bid for governor in 2010, and rode the anti-ObamaCare wave into office. Shortly after becoming governor, he announced he would not lift a finger to help the federal government implement the law. I followed all this pretty closely. I served on Scott’s gubernatorial transition team, at his invitation.

President Obama has won reelection, and his administration has asked state officials to decide by Friday, November 16, whether their state will create one of Obamacare's health-insurance “exchanges.” States also have to decide whether to implement the law's massive expansion of Medicaid. The correct answer to both questions remains a resounding no.

Today’s New York Times features an opinion piece by J.D. Kleinke of the conservative American Enterprise Institute. Kleinke’s thesis is that ObamaCare’s conservative opponents should stop complaining. “ObamaCare is based on conservative, not liberal, ideas.”

A study in this week’s New England Journal of Medicine finds that when three states expanded their Medicaid programs, mortality rates fell 6 percent relative to four neighboring states. The study found evidence that the mortality gains were concentrated in poorer counties — i.e., where people were most likely to become eligible for Medicaid.

Medicare and Medicaid are rife with fraud. We’re talking 10 percent or more of total spending, which is two orders of magnitude more than what credit card companies tolerate.
