Sen. Tim Scott of South Carolina filed paperwork on Friday to enter the 2024 Republican presidential race, testing whether a more optimistic vision of America’s future can resonate with GOP voters who have elevated partisan brawlers in recent years.The Senate's only Black Republican has made his grandfather’s work in the cotton fields of the Deep South a bedrock of his political identity. Yet Scott rejects the notion that racism remains a powerful force in society, and he has cast his candidacy and rise from generational poverty as the realization of a dream only possible in America.He is scheduled to make a formal announcement on Monday at Charleston Southern University, a private Baptist college and Scott’s alma mater, in his hometown of North Charleston.Scott tries to focus on hopeful themes and avoid divisive language to distinguish himself from the grievance-based politics favored by those leading the GOP field, such as former President Donald Trump and Florida Gov. Ron DeSantis.___Associated Press writer Thomas Beaumont in Des Moines, Iowa, contributed to this report.
