The state of Colorado has just passed a law that would require its electoral college to cast its votes for whichever presidential candidate receives the most total votes nationally. This makes 11 states which have so far passed similar measures. (Our own New Mexico, where LR Net is based, is considering a like-minded bill.)
There have been countless proposals that the electoral college be abolished since it rewards states that have small populations over those that have large ones. Republicans, which tend to be over-represented in low population rural states have fought such measures tooth and nail. To date, it has seemed that only a constitutional convention could rid the nation of the college, and that was highly unlikely.
However, with states like Colorado acting on their own in this way, the electoral college could be headed to the scrap heap, constitutional convention or no constitutional convention.
