One of the differences between a Republican system of governance and the Presidential Democracy is that in a Presidential Democracy the Head of State (the President) is always directly elected by the citizens and always directly selects ministers or selects the Prime Minister, who then selects the ministers. The second difference is that in a republican system the government may fall within a given electoral term, whereas in the presidential system the same head of state can elect another government (like in France, which would have to be approved by the parliament) or change ministers (like in the USA).
The future European Federation’s President needs such powers for two main reasons: to keep strict separation of powers and maintain a stability of the government, which in these challenging and unstable times is a top requirement.
