John McCain said in a speech that he would ask Congress for an American equivalent of the Prime Minister “Question Time” that occurs in many parliamentary governments. There have been some editorials on this from George Will and the New York Times as well as some blogging on the concept.
I think most people miss the point (although Mr. Will probably comes the closest to getting it right, in my opinion). In most Parliamentary Government systems, the voters elect the Parliament and they, in turn, elect the Prime Minister (in the UK countries this is slightly different in that the Monarch actually appoints the PM but in modern history the Monarch appoints the choice of the Parliament). So in this government, the Prime Minister serves at the pleasure of the Parliament.
