What ideological perspective(s) is/are presented in the following source?
"There would be fewer blunders involving society as a whole if big decisions were left entirely to the few political leaders who are naturally equipped with the insight, ability and charisma to deal with them"
The ideological perspective that most closely conforms to these ideas is elitism. One definition of elitism is that it is a political ideology that holds that some people are better equipped to rule than others and that these people should have the most power. This is the idea expressed in the passage you cite.
This idea has also been espoused by a variety of other ideologies. For example, the republicans/Federalists from the time that the Constitution was being written would have agreed with this statement. Alexander Hamilton was one of them and he believed that the mass of people were not really smart enough or wise enough to be given much of a say in government. Taken to extremes, this idea is espoused by totalitarian ideologies like fascism and communism.
So, this idea could come from a variety of ideologies that do not believe in full democracy. However, the best fit is elitism.
