Donald Trump is learning the hard way that winning primaries is not enough.  You also have to win delegates–and keep them–in order to win the nomination.  Trump narrowly won Louisiana’s presidential preference vote, but Ted Cruz appears to have emerged from Louisiana with more pledged delegates.  (Trump threatened to sue.)  Then, after Trump stated that he no longer intends to honor his pledge to support the eventual Republican nominee, his claim to South Carolina’s 50 delegates is in jeopardy.
