Put this on the list of strangest political endorsements ever: A former grand wizard of the Ku Klux Klan is supporting a former Black Panther in Tuesday's New York Democratic congressional primary.

Top Democrats are worried the race could make their party look bad.
 
Rep. Edolphus Towns is retiring from his seat representing parts of Brooklyn and Queens. In the race to replace him, Towns is endorsing Charles Barron, a former Black Panther who is also a New York City Council member.

Barron is running against New York Assemblyman Hakeem Jeffries.

Barron has compared Israel to the Nazis and called the Jewish nation "the biggest terrorist government in the world."

That is music to the ears of David Duke, former head of the Klan and also a one-time candidate for Louisiana governor.

Duke posted his endorsement of Barron on YouTube saying, "So, in a race for Congress between an anti-Zionist Black activist and a Black activist who is a bought and paid for Zionist Uncle Tom, I'll take the anti-Zionist any day."

Barron has rejected Duke's support

Still, a who's who of nervous New York Democrats have lined up to oppose Barron for the seat. Sen. Chuck Schumer and Gov. Andrew Cuomo are just a few of the top Democrats coming out to support Jeffries.
