Barack Obama signing the Patient Protection and Affordable Care Act at the White House. March 23, 2010

Dr. Nirav Shah, the New York State Health Commissioner, talks about the Affordable Care Act's health insurance exchanges, which go live today. Plus: Susan Page of USA Today on the government shutdown in DC and what comes next; Paul Danahar, former Middle East bureau chief for the BBC; and Ellen Futter, president of the American Museum of Natural History, on the museum’s new teacher training program. And we take your calls on today’s Public Advocate run-off as part of an Informal, Unofficial, Thoroughly Unscientific Exit Poll.
