Donald Trump mocked Nikki Haley's losses and rallied her supporters to join his cause after she suspended her campaign following a series of losses on Super Tuesday. However, Trump's influence appears to wane among some traditionally conservative voters. Republican leaders recognize Trump's need to bolster suburban support, with Senator Tillis providing tepid backing, while Senators Collins and Romney withhold full endorsement. The GOP's shift toward Trump's MAGA ideology risks alienating moderate and suburban voters, essential for winning elections.
