Evidently there's a proposal afoot in Colorado to scrap the winner-take-all system normally used to award Electoral Votes, and award one electoral vote per each Congressional District. From the Denver Post, the concept has some interesting ramifications:
If the concept had been applied in 2000, Al Gore would be president of the United States. President Bush received 51 percent of the vote in Colorado, meaning he would have received only four of Colorado's then-eight electoral votes.
Bush received a total of 271 Electoral College votes, just one more than needed to be elected. Take away four of his Colorado votes and Gore is president.
However, had the system been in place in California, where Bush collected 42 percent of the vote, the overall Electoral College race would not even have been close. He would have claimed 23 of that state's electoral voters, sending him way over the top.
