Can Donald Trump be stopped from winning the Republican nomination? The answer is yes. Despite his big win over Marco Rubio in Florida and his narrow wins over Ted Cruz in Illinois, Missouri and North Carolina, he has not won a majority of delegates yet awarded — 661 at this writing, with several more to be added when Missouri and Illinois congressional district totals are tabulated.

Any candidate needs to get a 1,237-delegate majority to be nominated. Trump needs to get a majority of delegates in the contests ahead to get there. The March 15 results show how that could happen. The question is what Republican voters who fear Trump’s nomination will damage the party, the nation or both will do about it.
