Moving up the Pace of Reform
When Congress passed Medicare in 1965, it went into effect one year later. In contrast, the major provisions of the health-care reforms now before Congress would not go into effect for three years (January 1, 2013, under the House bill) or four years (January 1, 2014, under the bill being voted on by the Senate).
The House's timetable is bad enough, but the Senate's timetable is, to put it bluntly, nuts. A four-year delay in delivering benefits from reform would give rise to widespread disappointment and confusion during the intervening years, and it would expose the entire program to the risk of being overturned in the 2012 election, if not in 2010.
When I worked at the White House in 1993 on the Clinton health plan, one of my responsibilities was to think through the "phase-in"--the series of steps that would be required to put the legislation into effect. I haven't been involved this time, but I don't think it's a deep mystery as to what is motivating the decision to delay the program, though it seems to me to invite more problems than it avoids.
