- ‘But Buckley's task was easier than Beinart's will be because the Birchers were never remotely as central to the Republican base as the Moore-MoveOn faction is to the Democratic base.’
- ‘The Birchers wanted to destroy both social security and the UN back in 1962.’
- ‘Beinart is bravely trying to do for liberalism what another magazine editor - the National Review's William Buckley - did for conservatism by excommunicating the Birchers from the conservative movement.’
- ‘William F. Buckley and other mainstream conservatives spent years isolating and discrediting the Birchers.’
- ‘But Moore is a hero to the Birchers because of views that are not expressed in the book.’
