Some pundits are now calling on Bush electors to “vote their conscience,” which translates to, “violate your pledge.” If an elector wants to vote that way, then he or she should run that way: “Elect me and I promise to vote for someone whom I will pick later.” However, every elector in this race has made one simple promise to the voters: “Elect me and I’ll vote for Bush, Gore, Nader, etc.” Electors should keep their promise. If they do not, Congress should refuse to accept the vote of the faithless elector and count that vote as it has been pledged, because faithless electors have deceived and disenfranchised those who voted for them.

The Electoral College system prevents candidates with only regional appeal from winning. Statistically, having to prevail in a number of sub‐​elections produces a better result for the country. For the same reason we count the number of games won in the World Series (rather than the total number of runs, which would be heavily influenced by one anomalous game). If team A wins the first game 11 runs to zero, and team B wins the next four games one run to zero, we all know that team B has won the World Series. After all, if Bush won 100 percent of the popular vote in his home state of Texas, thereby prevailing in the nationwide popular vote, those extra votes would not show he had more support nationwide, only that he is a candidate popular in one very populous state
