Basically, what is described below is a way to make the president elected by national popular vote - without actually amending the constitution.
Take a look:
http://writ.news.findlaw.com/amar/20011228.htmlBasically, what these Law Professors (Vikram David Amar and Akhil Reed Amar) say is for a coordinated state action: states would declare that all of their electors would be awarded to the winner of the national popular vote. However, the law would only take effect if enough other states chose to do the same thing. If enough states adopted a law like this, so that their combined electoral total would be at least 270 electoral votes, it works! Thus, the 11 largest states, comprising a majority of the electoral college could effect this change.
The law would look like this:
This state shall choose a slate of electors loyal to the Presidential candidate who wins the national popular vote, if and only if other states, whose electors taken together with this state's electors total at least 270, also enact laws guaranteeing that they will choose electors loyal to the Presidential candidate who wins the national popular vote. * Of course, they acknowledge there are likely to be some issues - however, they endorse a multistate effort then to set standards by which all the participating states agree to. This could be delegated to a non-governmental panel or to an interstate council. Potentially, even Congress could authorize it as an optional endeavor - however, it's likely that eventually, all states would take part and the EC would just become a meaningless vestigial institution with no effect, since it would just ratify the popular vote winner.
This is actually quite ingenius and though it sounds farfetched, since it would require fewer states to ratify this than the full 3/4 needed for an amendment, if popular-vote advocates actually pushed for this, it really could work.
