Those that say a Republic is better immune to idiots in power than a Monarchy should look at GWB and learn. An idiot can be bred as much as be elected for power.

At least the Monarch does not have to be concerned with public opinion, and therefore the means that manipulate public opinion. The notion that all governments should be elected and empowered by the people is not written in stone, neither it is necessarily the best; if the people are stupid, and if the people are easily manipulated by Big Money and Big Media into being swayed for demagogues or a certain candidate, then it's best to take away their right.

Which is probably one of the biggest problems out there. A perfect Democracy exists only in the realms of dream; in the United States the power of the top guys effectively enforces a two-party oligarchy ran by the same old interests.
