Former U.S. President Donald Trump won the Republican primary in North Dakota on Monday, according to projections from the Edison Research Center, before a series of contests known as Super Tuesday that are expected to solidify his lead in the race for the party's presidential nomination. Trump secured a comfortable victory in North Dakota over Nikki Haley, his last remaining competitor for the Republican nomination. Trump is expected to dominate today's contests as Republicans cast their votes in 15 states and one U.S. territory on the largest day in the primary election calendar. Haley, the former U.S. ambassador to the United Nations, achieved her first victory in the primaries on Sunday in Washington, D.C., but she does not appear to have favorable prospects for the nomination after Trump's wins in the first eight contests. He is anticipated to continue his winning streak in nearly all remaining contests. Trump is focusing on a potential electoral competition with current Democratic President Joe Biden in November.
