It's one of the many often attributed to Winston Churchill, though to my knowledge there's no actual evidence of him actually saying it and his other writings go against the sentiment. I don't know who actually did say it first
As others put, no, but it does remind me that Aristotle felt society should only be run by the most intelligent among us, hence the term Aristocracy.
Of course, in practice people make up bullshit rules to determine who is most intelligent and that messes up the whole concept (e.g. Jim Crow tests and such). But it's a nice fantasy if ever we could pull it off.
Marx grasped this essence of capitalist democracy splendidly when, in analyzing the experience of the Commune, he said that the oppressed are allowed once every few years to decide which particular representatives of the oppressing class shall represent and repress them in parliament!
