Excerpts from recent editorials in the United States and abroad: ___ May 6 The New York Times on Trump's comments about a possible third presidential term When Republicans took control of Congress in 1947, they were still angry that President Franklin D. Roosevelt had won a fourth term in 1944, and they set out to pass a constitutional amendment to limit future presidents to two terms. John Jennings, Republican of Tennessee, stood on the House floor and said a 22nd Amendment was necessary to prevent a dictator from taking over the country. “Without such a limit on the number of terms a man may serve in the presidency, the time may come when a man of vaulting ambition becomes president,” Mr. Jennings said on Feb. 6, 1947.
