Krugman, the Times Oped Page, and Obama

Will someone please explain to me why Paul Krugman has it in for Barack Obama? And why the Times oped page continues to devote its prime real estate to Krugman’s repeated attack? Here he is again today, for the third time in two months, excoriating Obama for compromising too much with insurance companies and drug companies in his health care plan, without mentioning that (1) HRC’s health care plan compromises at least as much, (2) all the leading Democratic plans are basically the same apart from mandates, which would apply to a tiny fraction of the currently uninsured, and (3) Obama’s may be marginally better than HRC’s if he’s correct in judging that the most of the currently uninsured couldn’t afford to pay HRC’s mandate anyway.
