While the term of elected Members of Parliament (lower chamber) is usually four or five years, in most presidential and semi-presidential systems, presidents are elected for a five-year or a six-year term. Particularly in the case of directly elected presidents in whose hands extensive powers are concentrated, longer terms may be critically questioned. It is no coincidence that worldwide most countries with seven-year terms for powerful elected presidents are autocratically governed. Whereas the Irish democracy with a president who is vested only with limited powers clearly does not fall into this category, examples of such electoral autocracies include Azerbaijan, Cameroon, Congo (Brazzaville) as well as Rwanda. This is even more problematic if there are no limitations on being re-elected.
