This prevented the overthrow or nullification of the actions of the government by the people, keeping the government strong and powerful. Further, Judicial Review was established under Thomas Jefferson in 1798 as a result of the case of Marbury v. Madison. This guaranteed that the government itself would never stray far from the constitutional ideals inasmuch as the Supreme Court - and not any other branch - had the final say on all questions of constitutionality. This protected the stability of the government by preventing it from straying too far from a stable democracy into, for example, an unstable dictatorship (dictatorships are generally characterized by constant overthrows) and also protected the rights and liberties of the people. This, therefore, ensured the support of the people of the government; as with any democracy, it is, by definition, the people who make the government tick.
Both Washington and Adams also aided the centralization of and the accumulation of authority of the US government, an essential element in any stable government. Washington's contribution, the Hamilton Plan, was of immeasurable value. Hamilton bolstered the national credit and the peoples' confidence in the government by having the government "fund the debt at par" (pay its debts off at face value), assume the debts of the states, and establish a national bank. Incontrovertible proof of the efficacy of his plan was the increase in government bond sales despite their depreciation. Because of this, the states and the people had a vested interest in the success of the government, and consequently, everyone stood to gain in strengthening and adding to the stability of the government. Because of this new universal interest in the governments' success, the government had the support of the people, and the support of the people is an essential element in securing the stability of a democracy.
