The Electoral College has outlasted its usefulness.
Voters living in a "red" or "blue" state but voting unlike the majority in that state are disenfranchised, because their vote doesn't count. Eliminating the Electoral College will mean that "swing" states will no longer receive all the attention and the campaign stops and the empty campaign promises.
Also, the electors are selected by the two main political parties, Republican and Democrat, disenfranchising all other voters, including independents, Libertarians, and Green Party members.
