What does arthur schlesinger, jr. say would happen if the electoral college was abolished?

According to Arthur Schlesinger, Jr., if the Electoral College of the United States was abolished, the collapse of the already weakened two-party political system would be fast tracked; resulting in multiplication of splinter parties. In his opinion, this would encourage single-issue ideologues (those who blindly support a particular idea or set of ideas) and eccentric millionaires to venture into the presidential race and make it difficult for major party candidates to win popular-vote majorities.
