The republicans charge that Democratic health care reform would, in Sen. Charles Grassley's words, "pull the plug on Grandma." According to Sen. Jon Kyl, the bills before Congress would ration medical treatment by age. Rep. John Boehner says they promote euthanasia. Sarah Palin has raised the specter of "death panels." Such fears are understandable. It's not preposterous to imagine laws that would try to save money by encouraging the inconvenient elderly to make an early exit. After all, that's been the Republican policy for years.
