South Carolina Gov. Nikki Haley (R) announced Wednesday that she is endorsing Marco Rubio for president, potentially giving the Florida senator a much needed bump in the state ahead of Saturday’s primary. 

But Donald Trump supporters in South Carolina’s lowcountry aren’t bothered that the real estate mogul lost the governor and rising GOP star’s endorsement. Voters at Trump rallies on Wednesday told ThinkProgress that Haley lost their support when she made the decision last summer to remove the Confederate flag from the state capitol, where it had flown for 54 years. And they said they will never forgive her.

“That’s history,” said Tammi Lawton, who attended Trump’s rally in Walterboro with four friends. “No matter which way you look at it, that is history. That’s Southern history, and she’s a stupid idiot.”
