I think there are a few things to consider when taking in Hillary's comments about Nancy Reagan regarding AIDS:
1. While the Reagans deserve intense scorn for their inaction (hundreds of thousands of people died while they did nothing--a great contrast to the action taken over a small group of people affected by tampered Tylenol), that isn't the entire picture (and the Advocate article below explains why).
2. Hillary was trying to speak kindly of someone (who is not a complete monster despite flaws and mistakes) on the day of their funeral and based on the Advocate article, her comments may not be entirely incorrect--just not a fully accurate picture.
3. Hillary would definitely have a different perspective (possibly inside knowledge) having been First Lady.
4. I do hope and expect a fuller response from Hillary that acknowledges the great pain & damage the Reagans caused before they finally took action on AIDS. I can't imagine the response to her comments won't merit such.
Overall, I don't think Hillary should be let off the hook, but she shouldn't be attacked either.
