Washington DC - South Carolina Senator Lindsey Graham warned Donald Trump to stop with his personal attacks on Kamala Harris or risk losing the 2024 election.

In a recent interview with NBC News, Graham was asked what he thought about former South Carolina Governor Nikki Haley's recent advice for Trump and Republicans to "quit whining" and stop "talking about what race Kamala Harris is."

Graham agreed with the sentiment, explaining that he believes a debate with Trump over policies would be a "nightmare" for Harris.

"Yeah... I don't look at Vice President Kamala Harris as a lunatic, I look at her as the most liberal person to be nominated for president in the history of the United States," he said.

"President Trump can win this election," Graham continued. "If you have a policy debate, he wins. Donald Trump the provocateur, the showman, may not win this election."

Since Harris entered the race, Trump and his running mate, JD Vance, have chosen to focus their attacks on Harris' character, gender, and racial heritage, which many critics have argued is a losing strategy.

At a rally in Pennsylvania on Saturday, Trump called Harris a "communist" and a "lunatic," mocked her laugh, and insisted he was "much better looking than her."

Graham went on to suggest that he, Haley, and other Trump allies should "get together and actually campaign for the guy, rather than just give advice."
