The Manhattan Democratic representative on the city’s Board of Elections was caught on a secret video slamming Mayor Bill de Blasio’s municipal ID program as contributing to “all kinds of fraud” — including at the polls.“He gave out ID cards, de Blasio. That’s in lieu of a driver’s license, but you can use it for anything,” Commissioner Alan Schulkin said in the undercover video recorded by a muckraker for conservative nonprofit Project Veritas.“But they didn’t vet people to see who they really are. Anybody can go in there and say, ‘I am Joe Smith, I want an ID card,’ ” he said in the bombshell tape.“It’s absurd. There is a lot of fraud. Not just voter fraud, all kinds of fraud . . . This is why I get more conservative as I get older.”Schulkin didn’t hold back to the undercover journalist, who identified herself as a political consultant at a United Federation of Teachers holiday party on Dec. 16.
