Nikki Haley‘s presidential campaign on Wednesday brushed off her mortifying defeat in Nevada’s primary and said the former United Nations ambassador would press ahead with her long-shot challenge to former U.S. President Donald Trump.

Haley lost Nevada’s Republican primary handily on Tuesday even though she was the only candidate listed on the ballot. She secured just 31% in the contest, well behind the 63% of the ballots cast for “none of these candidates,” according to Nevada election officials.

No delegates were at stake in the primary, making Haley’s defeat more symbolic than meaningful. Trump appears poised to capture all of Nevada’s 26 delegates when the state party holds a separate caucus proceeding on Thursday, which will further diminish Haley’s long-term prospects as a candidate.
