Mr. Nixon, having won the 1968 election in a squeaker, wished to manipulate the 1972 election to assure victory. Internal polling a year or two before the election indicated the only candidate over which he'd have a walk was Sen. George McGovern. Thus, the CREEP (Committee to Re-Elect the President) did what it could to aid the senator and harm his opponents.
In this, Mr. Nixon did nothing that Dammocraps haven't done before, and likely much less. But when it became apparent to the Republican leadership that Mr. Nixon had likely committed felonies, the Republican leadership informed Mr. Nixon that he had to go.
That is a critical difference between Republicans and Dammocraps. Republicans hold fast to the concept that the president may not be a felon. Dammocraps celebrate their felon presidents.
"wished to manipulate the 1972 election"? Rather odd choice of words. I disagree with the apparent conclusion you want us to reach concerning CREEP and its impact on the general election and the democratic nomination for President. The idea that CREEP helped influence the selection of McGovern as the Dem nomonee is pure conspiritorial nonsense.
Nixon was reelected overwhelmingly because the public supported his policies. In the 68 campaign, Nixon favored a negative income tax, which became the earned income tax credit and an expansion of the welfare programs begun during the Great Society, creation of the Environmental Protection Agency (EPA) with the Clean Air Act, dramatic increases in social service spending, and interventionist economic policies ranging from dollar devaluation to wage and price controls. During his presidency, many of these proposals became law, particularly those that could be accomplished without Congressional approval.
McGoverns platform was unapologetically liberal: he campaigned on an immediate end to the Vietnam War, socialized medicine, and a guaranteed national minimum income. The radicalism of the 1972 Democratic platform was caused partly by a sense inside the party that its defeat in 1968 was caused by a failure to articulate adequately the differences between the Democrats agenda and that of then-candidate Nixon.
