A constitutional amendment to clarify the way votes are cast in the Electoral College was necessary because
a) there was no way to tell which votes were for president and which were for vice president. b) electors were not pledged to candidates. c) large states did not have fair representation in the College. d) in practice, the House is not capable of making a decision on who will be president. e) the previous system allowed candidates to win even if they did not have a majority of the popular vote.
