Haley wins Super Tuesday election in Vermont despite losing elsewhere to Trump

That victory will do little to dent Mr. Trump’s primary dominance, however. The former President won 11 other states on Super Tuesday.

Ms. Haley is the last major rival to Mr. Trump standing in a once-crowded primary field. She has increasingly stepped up her attacks on the former President, arguing that he will lose in November to President Joe Biden if he clinches the party’s nomination.

On the Democratic side, Mr. Biden also ran up the score with wins all around the country against only token primary opposition — all but cementing the long-expected November rematch between him and Mr. Trump.
