Sen. Tim Scott (R-S.C.) speaks during a Faith in America tour event at Drake University in Des Moines on Wednesday. You can even call me ‘Uncle Tim.’ Just understand, your words are no match for my evidence,” he said Wednesday. Scott is widely expected to formally enter the presidential campaign in the coming months. Other potential Republican presidential candidates include former Arkansas governor Asa Hutchinson, former secretary of state Mike Pompeo and former vice president Mike Pence, who are also preparing prospective campaigns. If he enters the race, Scott will start with a significant financial advantage over many in the field.
