The flaws were with the interpretation of the system because many of the vaguer rules had never been tested instead of a concieted effort prior to the election, and are very unlikely to repeat themselves in the near future.
What do you mean never been tested?? Let me take you back to the year 1876, a republican called Rutherford B. Hayes was fighting against a democrat by the name of Samuel J. Tilden for the post of President of the United States. The first election result from 7 November 1876 indicated that Tilden was on course for a clear victory. He had won his home state, the swing states of Connecticut, New Jersey, and Indiana, and was expected to carry the solid South and most of the West. However a republican called Daniel Sickles realised that if Hayes lost no more Northern states and won Florida, Louisiana, and South Carolina he would win by one electoral college vote. Sickles rushed off telegrams to Republican leaders in those states, under the signature of Republican national chairman Zachariah Chandler, who was sleeping off a bottle of whiskey, urging them to hold their states for the Republicans. The early edition of the New York Times on November 8 characterized the election as undecided; The Results Still Uncertain, read the headline. Its second edition gave Hayes 181 electoral votes, with Florida too close to call. When the dust settled, Tilden had won the popular vote, with 4,284,020 (51%) to Hayess 4,036,572 (48%), a margin of less than 250,000. Tildens 184 electoral votes were one short of a majority, while Hayess 165 electoral votes left him 20 ballots shy of the presidency. The remaining 20 electoral votes were in dispute: one from Oregon and 19 from the three Southern states Florida (4), Louisiana (8), and South Carolina (7). In the three Southern states, both parties were claiming victory in close elections and charging the other party with vote fraud. Being the party in power in those states, the Republicans had a majority on the returning boards, which would certify the election results. They threw out enough Democratic votes to give the election in their states to Hayes. In Florida, the state supreme court ruled in favor of the Democratic gubernatorial candidate, but let Hayess margin of victory stand. The new Florida governor promptly appointed a Democratic returning board which announced that Tilden had carried the state. However Congress appointed a congressional committed to investigate. The committee decided to award all the disputed votes to Hayes. Hayes, in return, however, promised to end reconstruction. Hayes became the next President.
Funny how history can repeat itself.
