It was only weeks ago that Donald Trump appeared unstoppable in his bid for the Republican presidential nomination in the United States.  Although he had hardly won a majority of Republican voters in any state, his competitors were carving up the preponderant anti–Trump voting bloc in ways that allowed the tycoon to win primary elections in every part of the country, often with the support of only one in three voters.  That strategy worked ingeniously when the Republican field was heavily populated by competing presidential aspirants.  Now that the field has narrowed down to only three finalists, the intense opposition to Trump within Republican ranks has mobilised behind his two remaining competitors, probably blocking his path to victory.
