But as the president remains popular in South Carolina, the Democratic Senate hopeful has not gone after Trump directly, strategically avoiding the ideological battle lines that could drive voters here to Graham. It’s a gambit that has helped put Harrison within striking distance of a historic upset — and one that could provide a blueprint for Democrats trying to win in the South.

“Listen, I’m a Democrat. I understand that,” Harrison said in an interview as the sun set behind him over the Ashley River, an apparent acknowledgment of the headwinds his campaign has always faced. “But at the end of the day I’m a South Carolinian and I’m an American first.”…

Instead, Harrison is seizing on Graham’s conversion from Trump antagonist four years ago to portray the state’s senior senator as an unprincipled politician who has lost touch with South Carolinians.

“Lindsey thinks that he is the powerful one. But Lindsey is not powerful. Lindsey is like the moon. All he does is reflect the light of the sun,” Harrison told rallygoers at a park in North Charleston on Saturday.
