The race to replace crook Carl Kruger in the state Senate is getting down and dirty.

A YouTube video has surfaced of Councilman Lew Fidler, the Democratic nominee for the March 20 special election to represent southern Brooklyn, accusing Republican opponent David Storobin of having ties to “skinheads, and neo-Nazi groups and white- supremacist groups.”

And now Storobin, vice chairman of the Brooklyn GOP, is demanding an immediate retraction.

“Much of my family was wiped out by the Holocaust,” Storobin said.
