Nikki Haley suspended her presidential campaign on Wednesday after being soundly defeated by Donald Trump across the country on Super Tuesday.

This leaves the former President as the last remaining major candidate for the 2024 Republican nomination.

Haley didn’t endorse Trump in a speech in Charleston, South Carolina. Instead, she encouraged him to earn the support of the voters who supported her.

“It is now up to Donald Trump to earn the votes of those in our party and beyond it who did not support him. And I hope he does that,” she said. “At its best, politics is about bringing people into your cause, not turning them away. And our conservative cause badly needs more people.”

Her departure clears Trump to focus solely on his likely rematch in November with President Biden. The former President is on track to reach the necessary 1,215 delegates to clinch the Republican nomination later this month.
