I used every trick in the book.

我用上了生平所学。

The idea that an incumbent president should concede honorably and graciously and ensure a peaceful transfer of power, rather than trying to use every trick in the book to hang on to power, that's an American value too.

现任总统应该光荣而优雅地让步并确保和平移交权力， 而不是试图使用书中的所有技巧来保住权力，这也是美国的价值观。
