A friend of mine just returned from Connecticut, where he had spoken on several occasions on behalf of Joe Lieberman. He happens to be a liberal antiwar Democrat, just as I am. He is also a lawyer. He told me that within a day of a Lamont event--where he asked the candidate some critical questions--some of his clients were blitzed with emails attacking him and threatening boycotts of their products if they did not drop him as their attorney. He has actually decided not to return to Connecticut for the primary today; he is fearful for his physical safety.
HT to Mr. Reynolds, who has more on the subject.
Ms. Malkin has more.
