How a behind-the-scenes Washington political strategist sizes things up. Hint: Watch Ohio, Michigan, Pennsylvania, and Florida.

Since America's two-party system emerged in pretty much its present form in the election of 1828, the Electoral College has elevated the winner of the national popular vote 41 of a possible 43 times. One of the two times the Electoral College was "wrong," in 1876, it was not so much the Electoral College as the Republican-controlled Congress which pried away the presidency from Democratic nominee Samuel Tilden, as part of a Byzantine deal to bring Reconstruction to an end. The last time, or (depending on how you score 1876) the only time, the Electoral College differed from the popular vote was in 1888, when Republican Benjamin Harrison won the Electoral College while being edged out by Democratic President Grover Cleveland in the popular vote. In the subsequent twenty-seven consecutive presidential elections, the Electoral College winner has always been the candidate who finished first in the popular vote.

Given this history, it's no wonder most eyes glaze over at the very mention of the words "Electoral College." A relic of our founders' reservations about direct democracy in the late eighteenth century, a time when no such thing had ever been achieved beyond the confines of a city state, the Electoral College today is not a deliberative body, but a way of apportioning 535 voting units to the 50 states according to the size of their delegations to Congress, plus three electoral votes to the District of Columbia, the nation's capital that sends no voting members to either house of Congress. A majority of the total available electoral votes (270 of a possible 538) is required to elect a President. (If no majority is achieved, the House chooses the president and the Senate chooses the vice president.)

To the casual eye, then, the Electoral College appears an oddity of the election-night vote count, nothing more.

Yet every strategist involved in presidential politics becomes, of necessity, an expert in the Electoral College. And if the decision-makers who run the campaigns, up to and including the major-party nominees, are thinking about the Electoral College whenever they make a move concerning travel, campaign spending, and even issue selection, it'll be hard to know what's going on in the intense period that begins following the national conventions in August unless you have some sense of what makes the Electoral College so important to the participants.

The biggest single reality of the Electoral College is that the states can choose how to cast their electoral votes, and that almost all states choose to cast their electoral votes as a bloc on a winner-take-all basis -- from the 3 votes possessed by Wyoming and six other states, all the way up to the 54 cast by...
