I am not sure this is a new idea. The idea of annual parliaments was one of the original demands of the Chartists. Of course, regular elections are preferable to no elections. However, I am not yet persuaded that frequent elections necessarily benefit a country. Italy has been changing governments with greater frequency than most other countries since the war. Its record on crime and economic policy in particular, is not one which I would want my country to emulate.
Modern elections tend to be more about the style of presentation rather than a serious debate of policies. It is always tempting to say, "It couldn't possibly be worse." I fear that is always a dangerous assumption.
