"The President is merely the most important among a large number of public servants. He should be supported or opposed exactly to the degree which is warranted by his good conduct or bad conduct, his efficiency or inefficiency in rendering loyal, able, and disinterested service to the Nation as a whole. Therefore it is absolutely necessary that there should be full liberty to tell the truth about his acts, and this means that it is exactly necessary to blame him when he does wrong as to praise him when he does right. Any other attitude in an American citizen is both base and servile. To announce that there must be no criticism of the President, or that we are to stand by the President, right or wrong, is not only unpatriotic and servile, but is morally treasonable to the American public. Nothing but the truth should be spoken about him or any one else. But it is even more important to tell the truth, pleasant or unpleasant, about him than about any one else."
"President Theodore Roosevelt in the Kansas City Star", 149
May 7, 1918
Here are two more from T.R. that warrant cogitation
“There is no room in this country for hyphenated Americanism…. The one absolutely certain way of bringing this nation to ruin, of preventing all possibility of its continuing to be a nation at all, would be to permit it to become a tangle of squabbling nationalities.”
Speech before the Knights of Columbus, New York (12 October 1915).
“The death-knell of the republic had rung as soon as the active power became lodged in the hands of those who sought, not to do justice to all citizens, rich and poor alike, but to stand for one special class and for its interests as opposed to the interests of others.”
Labor Day speech at Syracuse, NY, Sept 7, 1903
