we have other parties. we have write in votes. we have options. problem is, so far, exercising those options has given us people like clinton and obama.
the milti-party system is basically what most of the European countries have. because no one can get a majority, nothing ever gets done. a great deal of time and effort is spent putting together a "coalition government", so that the various parties are not cutting each others throats, but if there is real work to be done, no decision can be made. all effort is put toward the compromise.
