 Many have argued in favor of single member district legislation on the grounds that it has appeared to them to lead to more stable government than other forms of representation. The thought is that proportional representation tends to fragment the citizenry into opposing homogeneous camps that rigidly adhere to their party lines and that are continually vying for control over the government. Since there are many parties and they are unwilling to compromise with each other, governments formed from coalitions of parties tend to fall apart rather quickly. The post war experience of governments in Italy appears to confirm this hypothesis. Single member district representation, in contrast, is said to enhance the stability of governments by virtue of its favoring a two party system of government. Each election cycle then determines which party is to stay in power for some length of time.
