Recognizing the strong regional interests and loyalties which have played so great a role in American history, proponents argue that the Electoral College system contributes to the cohesiveness of the country be requiring a distribution of popular support to be elected president, without such a mechanism, they point out, president would be selected either through the domination of one populous region over the others or through the domination of large metropolitan areas over the rural ones. Indeed, it is principally because of the Electoral College that presidential nominees are inclined to select vice presidential running mates from a region other than their own. For as things stand now, no one region contains the absolute majority (270) of electoral votes required to elect a president. Thus, there is an incentive for presidential candidates to pull together coalitions of States and regions rather than to exacerbate regional differences. Such a unifying mechanism seems especially prudent in view of the severe regional problems that have typically plagued geographically large nations such as China, India, the Soviet Union, and even, in its time, the Roman Empire.

This unifying mechanism does not, however, come without a small price. And the price is that in very close popular elections, it is possible that the candidate who wins a slight majority of popular votes may not be the one elected president - depending (as in 1888) on whether his popularity is concentrated in a few States or whether it is more evenly distributed across the States. Yet this is less of a problem than it seems since, as a practical matter, the popular difference between the two candidates would likely be so small that either candidate could govern effectively.

Proponents thus believe that the practical value of requiring a distribution of popular support outweighs whatever sentimental value may attach to obtaining a bare majority of popular support. Indeed, they point out that the Electoral College system is designed to work in a rational series of defaults: if, in the first instance, a candidate receives a substantial majority of the popular vote, then that candidate is virtually certain to win enough electoral votes to be elected president; in the event that the popular vote is extremely close, then the election defaults to that candidate with the best distribution of popular votes (as evidenced by obtaining the absolute majority of electoral votes); in the event the country is so divided that no one obtains an absolute majority of electoral votes, then the choice of president defaults to the States in the U.S. House of Representatives. One way or another, then, the winning candidate must demonstrate both a sufficient popular support to govern as well as a sufficient distribution of that support to govern.
