Proponents also point out that, far from diminishing minority interests by depressing voter participation, the Electoral College actually enhances the status of minority groups. This is so because the voters of even small minorities in a State may make the difference between winning all of that State's electoral votes or none of that State's electoral votes. And since ethnic minority groups in the United States happen to concentrate in those State with the most electoral votes, they assume an importance to presidential candidates well out of proportion to their number. The same principle applies to other special interest groups such as labor unions, farmers, environmentalists, and so forth.

It is because of this "leverage effect" that the presidency, as an institution, tends to be more sensitive to ethnic minority and other special interest groups than does the Congress as an institution. Changing to a direct election of the president would therefore actually damage minority interests since their votes would be overwhelmed by a national popular majority.
