Is Nancy Pelosi.
A problem with Medicare is that we all want to cut it in the sense of having it be less costly, though people like me want to cut it without reducing the quality of Medicare from the perspective of senior citizens. That's more about reforming our health care system generally than reforming Medicare, but as we saw in the last election even as Republicans want to destroy Medicare (and, yes, Villagers, they do), they can run as its defenders by criticizing all spending cuts even if they, in theory, don't reduce the quality of the program.
