"After 50 years at the center of all of this, I know that believing in the idea of America means respecting the institutions that govern a free society: the presidency, the Congress, the courts, a free and independent press. Institutions that are rooted not — they just — not to reflect the timeless words, but they re- — they — they echo the words of the Declaration of Independence: "We hold these truths to be self-evident." Rooted in the timeless words of the Constitution, "We the People." Our system of separation of powers, checks and balances, it may not be perfect, but it's maintained our democracy for nearly 250 years — longer than any other nation in history that's ever tried such a bold experiment. In the past four years, our democracy has held strong. And every day, I've kept my commitment to be president for all Americans through one of the toughest periods in our nation's history."
