What is the benefit to constitutional democracies when term limits on the executive are established?

The main benefit that constitutional democracies represent when time limits are established for the mandates of political representatives is that alternations are guaranteed. Thus, the generation of lifetime mandates by presidents, governors, etc., is avoided, guaranteeing the inexistence of cult of personalities within government, and preventing the formation of autocratic governments based on these cults.

the national congress's powers over the states were specific and definite: it had the sole power to negotiate treaties, declare war, and make peace. all powers not granted to congress were reserved for state governments. congress had no power to levy taxes, for example.

they were citizens but they could not vote and they did could not get involved into a political situation during that time.
