Vote suppression - insider tales

Democratic operative Bob Shrum is known as 0 for 8 for his record of no success in presidential bids. He has a recent book No Excuses. In it he tell of two cases he knows of intentional suppressing votes in 1980 and 2000. Via Politico with page numbers:

Shrum relates how l980 [Ted] Kennedy campaign operatives, posing as officials of the National Weather Service, phoned in to radio stations fake reports of a weather emergency to depress the Carter vote in southern Ohio. (No Excuses p. 113-114). Twenty years later, with the full support of the candidate, Gore campaign operatives manufactured traffic jams to obstruct the Bradley vote in southern New Hampshire. (Id. p. 324.)
