Former U.N. ambassador exits the potential Republican field as JD Vance and Marco Rubio emerge in early 2028 polling. Former South Carolina Gov. Nikki Haley has ruled out a second campaign for the White House in 2028, becoming one of the first prominent Republican figures to publicly close the door on a potential presidential bid as political attention shifts toward the next election cycle.
Haley, who served as U.S. ambassador to the United Nations during President Donald Trump’s first administration, confirmed that she would not seek the Republican presidential nomination in 2028. “I am not running in 2028, but I will continue to talk about the things that I care about,” Haley told CNBC. She added that she would continue advocating for policies she supports and backing candidates she considers appropriate.
Her announcement comes as the Republican Party begins considering its post-Trump leadership and potential candidates for the 2028 presidential election. Haley’s decision is particularly notable because she represents a traditional, establishment-oriented Republican wing that has sometimes differed with Trump’s political approach.
Haley’s 2024 presidential campaign: A final challenge to Trump
Haley’s decision to leave the 2028 field follows her unsuccessful attempt to secure the Republican nomination in 2024, when she became Trump’s last major challenger.

She entered the presidential race in February 2023 after serving as South Carolina governor from 2011 to 2017 and U.S. ambassador to the United Nations from 2017 to 2018. Her campaign emphasized conservative economic policies, national security, immigration enforcement and generational change in American politics. She also questioned Trump’s age, legal controversies and ability to attract independent voters.
Despite her campaign’s fundraising and support among some moderate and independent Republican voters, Trump maintained a substantial advantage in most state contests.
Haley secured two notable primary victories:
Washington, D.C.: She won the Republican primary on March 3, 2024, receiving 62.8% of the vote and all 19 delegates.
Vermont: She defeated Trump on March 5, receiving 49.32% against his 45.13%, according to official state results.
However, Trump dominated Super Tuesday on March 5, winning most of the Republican contests. Haley suspended her campaign on March 6, 2024, without endorsing Trump. Her exit left Trump as the presumptive Republican nominee.
Who could replace Haley in the Republican field?
Haley’s departure leaves an opening for Republicans who want to represent a more traditional conservative approach, although the early 2028 conversation is increasingly centered on two serving members of Trump’s administration.
The poll reportedly provides an early indication of how Republican voters view potential contenders.
| Republican figure | Share rating them an excellent candidate |
|---|---|
| Marco Rubio | 45% |
| JD Vance | 43% |
| Ron DeSantis | 32% |
The poll surveyed 1,705 U.S. adults, including approximately 500 registered voters from each party. The margin of error for Republican and Democratic voters was five percentage points. These are candidate evaluations, not predictions of primary results.
Other potential Republican contenders include:
- Donald Trump Jr.: The president’s eldest son is frequently discussed as a possible successor to his father’s political movement.
- Ron DeSantis: The Florida governor previously challenged Trump in the 2024 Republican primary and remains part of the 2028 discussion.
- Ted Cruz: The Texas senator has been mentioned among Republicans considering another presidential campaign.
- Rand Paul: The Kentucky senator has indicated interest in considering a 2028 campaign.
- Brian Kemp: The Georgia governor represents a more traditional conservative Republican political constituency.
2028: A succession contest taking shape
The Republican nomination process could eventually narrow into a series of direct contests between candidates as the field develops and contenders withdraw or consolidate support. However, it is too early to establish which candidates will reach that stage.

Vance and Rubio are attracting particular attention because of their positions in the current administration. Vance is vice president, while Rubio serves as secretary of state and has additional national security responsibilities. The central political question for Republicans is whether the party will continue Trump’s political approach or seek a candidate who can appeal to voters looking for a different direction.
Haley’s decision removes one prominent potential candidate from that debate. Her continued involvement in Republican politics, however, means she could still influence discussions about the party’s direction and its future candidates.
The Democratic field is also taking shape. According to a report, former Transportation Secretary Pete Buttigieg and Georgia Sen. Jon Ossoff each received a 29% excellent-candidate rating among Democratic voters. Former Vice President Kamala Harris and California Gov. Gavin Newsom each received 23%, while Rep. Alexandria Ocasio-Cortez received 15%. None of these figures has formally launched a 2028 presidential campaign yet.
