"... AIPAC, just about the most undemocratic setup it's possible to conceive of?"

What total bullshit! AIPAC is a legal lobbying organization in the United States. It has all the rights to expression of its wants and desires to Congress as, for instance, CAIR, NOW, unions, NAACP, the AMA, just to name a few. They are neither more nor less democratic than those organizations. You may not like that or the organization, but, then, I'm not surprised: AIPAC's aims don't agree with Mr. Shaw's.
