“Don’t cut Medicare. The reform bills passed by the House and Senate cut Medicare by approximately $500 billion. This is wrong.” So declared Newt Gingrich, the former speaker of the House, in a recent op-ed article written with John Goodman, the president of the National Center for Policy Analysis.

And irony died.

Now, Mr. Gingrich was just repeating the current party line. Furious denunciations of any effort to seek cost savings in Medicare  death panels!  have been central to Republican efforts to demonize health reform. What’s amazing, however, is that they’re getting away with it.

Why is this amazing? It’s not just the fact that Republicans are now posing as staunch defenders of a program they have hated ever since the days when Ronald Reagan warned that Medicare would destroy America’s freedom. Nor is it even the fact that, as House speaker, Mr. Gingrich personally tried to ram through deep cuts in Medicare  and, in 1995, went so far as to shut down the federal government in an attempt to bully Bill Clinton into accepting those cuts.

After all, you could explain this about-face by supposing that Republicans have had a change of heart, that they have finally realized just how much good Medicare does. And if you believe that, I’ve got some mortgage-backed securities you might want to buy.
