Well that Frum story is a bit more interesting when you add in this tidbit from Bruce Bartlett:
Since, he is no longer affiliated with AEI, I feel free to say publicly something he told me in private a few months ago. He asked if I had noticed any comments by AEI “scholars” on the subject of health care reform. I said no and he said that was because they had been ordered not to speak to the media because they agreed with too much of what Obama was trying to do.
