text: There is always the chance of a dispute- it happened in 2000- but with this method its less likely. As stated in sourse 3 by Richard A. Posner he sets the 2012 election as an example by saying "Obama received 61.7 percent of the electoral vote compared to only 51.3 percent of the popular votes."  That's 10.4 percent more than popular voting methods. Posner also adds " A tie in the nationwide electoral vote is possible because the total number of votes--538-- is an even number, but it is highly unlikely..." With the Electoral College there is certainty of outcome.
