Congressional contender Charles Barron, a former Black Panther, has been endorsed by the last man he’d want as a supporter — ex-KKK leader David Duke.

In a video rant on his Web site, Duke names Barron as his choice to succeed Brooklyn Rep. Ed Towns, citing the councilman as a likeminded foe of Israel.

He described Barron’s opponent, Assemblyman Hakeem Jeffries, as “a complete Zionist sellout.”

Jeffries attacked the comments as repugnant. Barron called it all “foolishness and stupidity.”
