I think the Republicans and conservatives generally were alienated by America's unsuccessful effort in Vietnam, and a lot of them, as Henry Kissinger admitted the other day, never got over President Nixon's impeachment, and didn't think, even though there was a pattern of illegal conduct there, sanctioned by the White House and proved by the tapes and other documentary evidence and testimony, they didn't believe that the impeachment was justified, and they didn't think he should have resigned.
