This Wednesday night, former “PBS NewsHour” anchor Jim Lehrer will host the first of three debates between President Obama and Mitt Romney. The debate will be divided into six 15-minute segments, with Lehrer beginning each by posing a question to the candidates, who will each have two minutes to respond. Lehrer will then direct the conversation for the remaining time in each segment.

Lehrer will have sole discretion to choose the topics and questions for each of the segments in the first debate. But he has already announced the debate will focus on “the economy, health care, governing and government’s role in people’s lives.”
