Exploring the Effects on the Electoral College of National and Regional Popular Vote Interstate Compact: An Electoral Engineering Perspective

The main purpose of this paper is to explore the consequences of the formation of either a Regional Popular Vote Interstate compact or a National Popular Vote Interstate compact on the functioning of the Electoral College. The two versions of interstate Compact which are considered here differ in only one respect: in one case the interstate compact allocates its electoral votes to the regional popular winner while in the other case it allocates these votes to the national popular winner. They both differ from the ongoing National Popular Vote Interstate Compact as it is assumed that the agreement is effective as soon as the members sign it. The decisiveness and welfare analysis are conducted for a simplified symmetric theoretical version of the Electoral College where the malapportionment problems are absent. The three most popular probabilistic models are considered and the study is conducted either from the self-interest perspective of the initiators of the interstate compact or from a general interest perspective. The analysis combines analytical arguments and simulations
