AARP, which backed the Bush Administration's prescription drug program, is now supporting some changes along the lines of what the Democrats (and a few Republicans) were pushing:

Here are some of the key passages from an AARP open letter to the pharmaceutical companies:
"...it is time for the industry to cooperate with secure, reasonable drug importation legislation, subject to proper oversight of the FDA (with additional authority and resources) and with strict procedures to ensure safety. This is an issue of top interest and concern to our members and to the American public. In a recent AP poll, nearly two-thirds of those surveyed said the government should make it easier to buy drugs from Canada or other countries. Our own surveys show similar results."
"...while the new Medicare law is designed to achieve substantial discounts through negotiations by the private plans, it is also prudent to provide the Secretary of HHS with appropriate negotiating authority in the event that the competitive private purchasing system does not produce the anticipated cost savings. Therefore, we are asking you to not oppose legislation to make this possible."
