Via RWN, an excerpt from Ann Coulter's Guilty: Liberal "Victims" and Their Assault on America :
"The sort of skullduggery for which Nixon was crucified was standard practice in modern politics. Presidents Roosevelt, Kennedy, and Johnson had used the FBI and Justice Department to harass their enemies and tap their phones -- often with the gleeful connivance of the media. NBC bugged Democratic headquarters in 1968. President Lyndon B. Johnson openly committed voter fraud to win elections in Texas, and he bugged Barry Goldwater in 1964. JFK's arm's-length attorney general Bobby Kennedy asked the FBI for files on steel company executives and sent agents to their homes to harass them. LBJ assistant Bill Moyers, now of PBS News, monitored the FBI's bugs on Martin Luther King's hotel room, distributing the tapes to select members of the Johnson administration as well as the press. Moyers also ordered the FBI to gather information about the sexual proclivities of Goldwater's staff. A decade later, President Jimmy Carter wanted to make Moyers director of the CIA. I guess it was just the press's 'judgement' to flip from toadies to a howling lynch mob when Nixon became President."
