Mark Evanier pointed out this article http://http://www.usatoday.com/news/politicselections/state/colorado/2004-08-16-colo-electoral_x.htm in USA TODAY, which talks about Colorado trying to change their electoral votes are distributed. It would make a difference in the up-coming Presidential election, if passed.

Mark is right that there would likely be a Supreme Court challenge by the loser, but I think that some changes should have been made nationally. Of course, the GOP is happy with how things stand and the Republican led Congress certainly wouldn't want to do anything which might infranchise Americans.
