When a contest between two candidates is very
close, people are less likely to vote and in return, the candidate with a
lesser support and is expected not to win may win instead. Because people will
be expecting that the two contending and strong candidates will win anyway because
many people are expected to vote them. So other people will choose to vote the
lesser candidate, trying to even the probability of the strong winning streaks
of the other candidates.
