"Nikki Haley Gains Key Endorsements Ahead of Super Tuesday Primary Battles"

Senator Susan Collins of Maine has endorsed Nikki Haley over former President Donald Trump in the upcoming Republican presidential primary, making her one of the few members of Congress to back Haley. Collins, a longtime Trump skeptic, praised Haley's qualifications and leadership qualities, contrasting sharply with the rest of her party, which has largely supported Trump. Despite Collins' endorsement, Trump maintains a significant lead in national polls, and Haley faces an uphill battle in the upcoming primaries.
