That's a more conservative bill than one we might otherwise get, but spending an extra $400 billion can hardly be considered "conservative".
OH, but it is. You seem to be overlooking the point that the Baby Booomers hold about 12

As they retire, and means testing is implemented, you begin to change the nature of Medicare, from an entitlement, to a social saftey net.
That is far more conservative than leaving it alone....
I doubt you would say that if we were spending it on the military.
