If a man is fit to be President, he will speedily so impress himself in the office that the policies pursued will be his anyhow, and he will not have to bother as to whether he is changing them or not

Context

“In each case there had been a reversal of party policy, and a nearly immediate and nearly complete change in the personnel of the higher offices, especially the Cabinet. I had never felt that this was wise from any standpoint. If a man is fit to be President, he will speedily so impress himself in the office that the policies pursued will be his anyhow, and he will not have to bother as to whether he is changing them or not; while as regards the offices under him, the important thing for him is that his subordinates shall make a success in handling their several departments. The subordinate is sure to desire to make a success of his department for his own sake, and if he is a fit man, whose views on public policy are sound, and whose abilities entitle him to his position, he will do excellently under almost any chief with the same purposes.” source
