This compact is a bad idea for implementing said goal. First an amending the constitution requires 3/4ths of states to agree to an amendment. This would make a fundamental change with less than half of the states. Secondly, it also possibly unconstitutional. Third, it's unenforceable a state can join and if they fail to follow the agreement other members can't do anything. Fourth, due to the questions of constitutionality when this takes effect it's going to leave the result of an election in legal limbo for possibly years. This is a big problem since the president is inaugurated only a few months after the election. Fifth, it easy for other states who are not a member to make it useless. For instances lets say Idaho decides only to publish their their electoral votes, and keep the actually number of votes secret for six months. It is no longer possible to determine who won the popular vote (in a timely manner).
