"Sununu's Endorsement of Haley: A Last-Ditch Effort to Challenge Trump's Dominance in GOP Primary"

Republican Governor Chris Sununu of New Hampshire has endorsed former ambassador to the United Nations and former South Carolina Governor Nikki Haley in the GOP presidential nomination race. Sununu's endorsement could potentially sway Republican voters, as well as independents and moderates who play an influential role in New Hampshire's crucial presidential primary. However, despite the endorsement, former President Donald Trump continues to hold a significant lead in the polls. Sununu's backing of Haley follows her recent endorsement by Americans for Prosperity Action, the political wing of the influential Koch Brothers' fiscally conservative network.
