This would not be the only time that Nixon would bestow special favors upon the Bush family. Six months earlier, as the GOP presidential candidate, he had seriously considered Poppy as a potential running mate, even though the latter was just a freshman congressman. Two years after W.s date with Tricia, following Poppys second unsuccessful bid for the U.S. Senate, Nixon named him his ambassador to the United Nations. And two years later, with President Nixons nod, Poppy served a stint as chairman of the Republican Party. It was a quick rise from relative obscurity to the highest level of national politicsand all with Nixons help.
Taped conversations reveal that Nixon considered Poppy Bush a lightweight. Nevertheless, he repeatedly pushed Poppy ahead, often over people who were much more qualified. This put the elder Bush on the upper rungs of the ladder to the presidency. In all probability, had Nixon not so favored Poppy, he never would have reached the top. And had Poppy Bush not been president, his son George W. Bush almost certainly would not have either.
In no small way, Richard Nixon helped to create the Bush presidential dynasty.
What disposed Nixon so positively toward the Bushes? A little-known fact, certainly missing from the many splendid biographies of the thirty-seventh president, is the likely role of Poppy Bushs father, Prescott, in launching Nixons own political career.
