With either of the three families claiming the throne (legitimists, orleanists, bonapartists), I personally think for France would be much better than it is now, with this republican system.
This type of republic, presidential (like the U.S) or half-presidential like in France, is a catastrophy. It would be much more normal a parlamentary system, with a strong prime-minister who actually governs the country.
Why spend so much money and efforts in those presidential election campains, with so many manipulations, in media, on TV, with stupid tv-debates between the candidates? Why the whole pathetic circus?
In fact it's a system created by the politicians for them, the politicians, to have access to more power, influence, control. To not be bothered by some monarchs. Why not have some president who can be easily controlled, or blackmailed?
It's already proven that the constitutional monarchies are the most democratic, stable and modern forms of government.
I really can't understand why would someone prefer a republic...
