Newly obtained dash cam video has thrown South Carolina’s gubernatorial race into turmoil after revealing the bizarre arrest of the state’s leading Democratic contender — a respected local attorney who was stopped while wearing nothing but underwear and shoes, proclaiming himself “God” and “Superman,” and verbally threatening political rivals.

William “Mullins” McLeod, 53, had announced his candidacy just days before the May incident became public this week through a Freedom of Information Act (FOIA) request. The footage shows McLeod shouting incoherently in downtown Charleston, ignoring repeated police commands, and launching a profanity-filled tirade at officers.

According to the police report, McLeod displayed “extremely bloodshot and highly dilated” eyes — symptoms “typical of an individual under the influence of a stimulant narcotic.” Officers said he was “yelling at the top of his lungs” when approached.

Rather than provide identification, McLeod repeatedly told officers, “Superman sounds good,” and “I’m one of the most just humans to ever walk this soil.” At one point, he threatened to “kick your f–king teeth in” — a remark apparently directed at Republican Attorney General Alan Wilson, who is also running for governor.

The Democratic hopeful also used the n-word during the confrontation and refused to exit the patrol vehicle once at the jail, telling officers, “No, I’m not getting out of this car. It’s time to go to bed.” He was ultimately dragged from the car and booked after 1 a.m., according to the New York Post.

McLeod — a former Charleston Democratic Party chairman who unsuccessfully ran for governor in 2010 — now faces misdemeanor disorderly conduct charges. The Democrat establishment appears eager to distance itself.

South Carolina Democratic Party Chair Christale Spain issued a statement calling on McLeod to end his campaign:

“After reviewing the transcript of the dash cam footage from his recent arrest, it is clear that Mr. McLeod is navigating profound challenges and should focus on his mental and emotional well-being instead of a campaign for governor. We offer him compassion and pray he finds the support he needs.”

McLeod’s campaign has yet to formally comment. In a recent interview announcing his candidacy, however, he claimed the arrest was “unlawful” and insisted that voters will eventually see it as proof he should be governor:

“The only thing I’d ask the voters is to please give me a little bit of grace and know that long before we go to Election Day, they’ll know exactly what happened. And when they learn what happened around my unlawful arrest, it will be a reason why I absolutely need to be our state’s governor.”

He further argued that he was merely exercising his “God-given, constitutional right to be in a public place” when taken into custody.

The shocking footage and the Democrat candidate’s defiance are already sparking comparisons to the left’s broader credibility crisis — where law-and-order applies to political opponents, but is conveniently overlooked for their own.
