The American system, especially the Electoral College, was designed to promote stability, to make sudden political change difficult. This made sense back in the 18th century, when political stability was often hard to come by, and the American Republic was young and subject to being swayed by small pressure-groups, newcomers, religious fanatics, and so forth.
However, the stability promoted by the Electoral College is now far more a liability than asset. Change is exactly what America needs today...the present system is ossified beyond redemption, with the Demopublicans endlessly recirculating the same ideas and the same faces. We haven't had a truly innovative, radical idea implemented or even seriously considered in America for what...forty years now? Even the two parties are increasingly looking alike. And the status quo--deficit spending, adventurism, and increasing statism--is killing us.
