I have often thought then when two candidates get more then 40 percent of the vote, the election should be decided by a flip of a coin. This would discourage manipulation of election laws, gamesmanship, and rigging of elections and ensure the majority voice is heard most of the time. It also would have a moderating impact on elections.

As when one candidate gets 49% and other gets 51%, the truth is the majority supports either one of the candidates. The difference between is really just due to rounding error and random noise –  going between the most two popular candidates ensures popular voices always have a chance to represent us in government.
