One GOP operative in the state told me those fundraising numbers from Harrison’s campaign have left Republicans in the state “stunned” and that it is absolutely on track to be the most expensive race in South Carolina history, expected to top upwards of $40 million.

“He’s a very dangerous candidate to Sen. Graham,” the Republican strategist said, calling Harrison “the best Democratic candidate I’ve seen here in a very long time.”

Others, understandably, remain skeptical, even given Harrison’s strengths.

“I just don’t think the math works out in Jaime’s favor at this point,” another South Carolina GOP strategist said. However, the operative did admit that “Lindsey is going to have to work harder than he ever worked before,” but that “Jaime would have to run a perfect race, and Lindsey would have to make a lot of mistakes” to win.
