Are our leaders becoming dumber?

Usually I stay away from politics, but I'll make an exception from time to time. After listening to a speech of former US president Bill Clinton I have to wonder how people could choose a man who can't put talk for 10 minutes in front of a crowd without making some pronunciation or grammatical error after they had a president who could speak articulately and coherently and respond to non-scripted questions in an intelligent manner.

This isn't a US-only phenomenon. Closer to home, both in Hungary and Romania the current leaders are mentally less capable than the former ones. A sad story from the last elections in Hungary - when they asked a voter why he voted against the former leader he said something along the lines of: when he spoke he used words which I could not understand. I want a president that speaks my language! - all I can say is: get a dictionary.
