Would abolishing the Electoral College cause the winner of the election to lack a strong public mandate or approval?
As the system currently stands, few Presidents ever obtain a strong mandate in their general election (the higher the percentage of the popular vote, the stronger the mandate). However, with the system that FairVote: The Center for Voting and Democracy advocates, Instant Runoff Voting, the President-Elect will always have a strong mandate because he will always be elected through obtaining a majority (not just a plurality) of the popular vote.
