In his election-night victory speech, Barack Obama said he would be a president for all Americans, not just those who voted for him. But as a candidate he didn't campaign with equal vigor for every vote. Instead, he and John McCain devoted more than 98% of their television ad spending and campaign events to just 15 states which together make up about a third of the U.S. population. Today, as the Electoral College votes are cast and counted state-by-state, we will be reminded why. It is the peculiar mechanics of that institution, designed for a different age, that leave us divided into red states, blue states and swing states. That needs to change.

The Electoral College was created in 1787 by a constitutional convention whose delegates were unconvinced that the election of the president could be entrusted to an unfiltered vote of the people, and were concerned about the division of power among the 13 states. It was antidemocratic by design.

Under the system, each state receives votes equal to the number of representatives it has in the House plus one for each of its senators. Less populated states are thus overrepresented. While this formula hasn't changed, it no longer makes a difference for the majority of states. Wyoming, with its three electoral votes, has no more influence over the selection of the president or on the positions taken by candidates than it would with one vote.

We often forget that the power to appoint electors is given to state legislatures, and it is only because they choose to hold a vote that Election Day is at all relevant for us. Nowhere is a popular election constitutionally required. And, as the 2000 election reminded us, the winner of the popular vote is not guaranteed to become president.

The Constitution is no longer in line with our expectations regarding the role of the people in selecting the president. Yet several previous attempts to eliminate the Electoral College through a constitutional amendment have failed, scuttled by the difficulty of the process itself and the tyranny of small-state logic.
