Ahead of last night’s debate, the Obama campaign was already making plans for Vice President Joe Biden’s next speaking engagement in the tri-state area. Biden will attend an event at the Kent, Conn., home of Sally and architect Tony Zunino tomorrow with a performance by Audra McDonald and tickets costing up to $10,000. Michelle Obama will swing into New York on Oct. 17 for an evening on Park Avenue of performances by “presidental actors” — we can only guess that means brilliant “SNL” impersonator Jay Pharoah. The first lady will then head to the Long Island Marriott in Uniondale.
