The city’s Board of Elections has learned from its mistakes in September’s primary, so voters should expect a much smoother experience when they go to the polls in today’s general election, board officials said yesterday.

Critics, however, remain skeptical that there won’t be more serious snafus.

Election Board Commissioner J.C. Polanco said he and the other nine commissioners had been assured by the staff that voters won’t encounter the kind of problems that led Mayor Bloomberg to denounce Primary Day as a “royal screw-up.”

Those problems included voting sites that opened hours late, poll inspectors who ignored privacy concerns associated with the new paper ballots, and untrained workers who provided incorrect information.

“I feel the major issues we encountered in the primary have been addressed,” said Polanco, a Bronx Republican.

He said better coordination with the NYPD and school officials should take care of the delayed openings and the retraining of poll-site supervisors should ensure privacy. Principals have been asked not to unilaterally switch voting machines’ locations within their schools.
