Watch: Mitch McConnell Is 'Cocaine Mitch,' GOP Senate Candidate Don Blankenship Says in Bizarre Campaign Ad

GOP Senate candidate Don Blankenship of West Virginia released a bizarre new political ad on Monday in which he branded Senate Majority Leader Mitch McConnell "Cocaine Mitch" without explanation.

Blankenship, who is positioning himself as the anti-establishment candidate, released the ad with just over a week to go before the Republican primary, on May 8. The coal magnate previously spent a year in prison following an explosion at his mine that killed 29 workers, a stint he references in the ad and blames on Washington insiders.

"Politicians are running a lot of crazy ads," the Senate hopeful says in the promotional spot, backed with a country melody. "They blew up the coal mines and then put me in prison. Now they're running ads saying the coal mine blew up, and I went to prison. There's no surprise there."

Toward the end of the 30-second ad, Blankenship refers to the majority leader as "Cocaine Mitch" while talking about making children a priority.

"One of my goals as U.S. senator will be to ditch Cocaine Mitch," he says. "When you're voting for me, you're voting for the sake of the kids."

Blankenship, who did not immediately return Newsweek's request for comment, is lagging in the polls behind Representative Evan Jenkins and Attorney General Patrick Morrisey, but it's McConnell who has shaped up to be one of the Senate hopeful's most formidable political foes. The congressman has links to a super PAC that ran ads accusing Blankenship's mines of poisoning drinking water and also told The New York Times he didn't want the coal magnate—who hasn't released financial disclosure forms—to nab the Senate seat.

Aside from dubbing him "Cocaine Mitch," Blankenship previously floated accusations that McConnell may be corruptible to Chinese influence, a racially charged attack that centers on McConnell's wife, Transportation Secretary Elaine Chao.

"I have an issue when the father-in-law is a wealthy Chinaperson," Blankenship said during a West Virginia radio show. "...There's a lot of connections to some of the brass, if you will, in China."
