Read the excerpt from president lyndon johnson’s speech in 1968.
there is division in the american house now. there is divisiveness among us all tonight. and holding the trust that is mine, as president of all the people, i cannot disregard the peril of the progress of the american people and the hope and the prospect of peace for all peoples, so i would ask all americans whatever their personal interest or concern to guard against divisiveness and all of its ugly consequences. . . .
with america's sons in the fields far away, with america's future under challenge right here at home, with our hopes and the world's hopes for peace in the balance every day, i do not believe that i should devote an hour or a day of my time to any personal partisan causes or to any duties other than the awesome duties of this office—the presidency of your country. accordingly, i shall not seek, and i will not accept, the nomination of my party for another term as your president.
