PBS president/CEO Patricia Kerger touted PBS’ commitment to children’s programming at today’s TCA sessions, but was questioned about why more of the network’s children’s series do not have lead female characters. Kerger said the network is planning a series about mathematics with a girl character in the lead. She declined to reveal details about the show.

The network has also added two programs to its 2012 election lineup this fall: America by the Numbers: Clarkson Georgia with Maria Hinojosa, exploring demographic changes in America, and Constitution USA with Peter Sagal. Sagal, host of NPR’s Wait, Wait … Don’t Tell Me, will travel across the country on a Harley Davidson to see how the American Constitution is, and isn’t, working.
