Consent of the Governed
Any form of democracy involves citizens in decision-making for the country. Voters agree to the system of elections which gives the winners legitimate authority.
Experience in Government
We the People can elect wise leaders who can use their knowledge and experience to help the country. If we constantly evaluate our elected leaders, we can make sure the right people are in charge.
Balance of Power
Modern republics use federalism (layers of government) and branches of government (executive, judicial, and legislative) to enforce the Rule of Law. By de-centralizing power, the idea is that everybody is held accountable by the laws and constitution.
Requires Constant Attention
When Benjamin Franklin said "A Republic, if you can keep it," he was referring to the fact that simply establishing a Republic is not enough to ensure its survival. People have the power in a Republic, and with great power comes great responsibility. It requires constant attention by the people to make sure a Republic is operating as intended.
Information Gap
As modern republics have entered the digital age, large parts of their populations have developed huge differences in their understanding of basic facts. If a population can't agree on what's true, they are going to stuggle to elect truly wise representatives.
Gridlock and Division
Going into our 250th year as a republic, the US faces intense partisan gridlock. This means the two major political parties are so divided on important issues that they rarely work together. This increases the "left vs right" divide in the country, which has led to government shutdowns, so-called "culture wars," and occasionally even violence.
