Most in the national news media are talking about how Donald Trump is now the clear Republican frontrunner and will be nearly impossible to stop. They are only partially right.

Trump, who won South Carolina (and all of its delegates) with a little under one-third of the vote, certainly is the front-runner. He has won two of the first three contests and has a clear lead in delegates. He should do well on March 1, when many Southern states hold their primaries and more than 600 delegates are at stake. By definition, that makes him the front-runner.
