Jim Lehrer Hoping to Provoke Discussion at Debate

But that's where gaffes come from!

Millions of Americans will – presumably – tune in for tonight's debate, the first between President Obama and GOP presidential candidate Mitt Romney.

They're hoping for some political theater, hopefully some new insight into the candidates' views and policies and character, and perhaps a gaffe or game-changing moment.

But – while there may be some freewheeling conversation between Messrs. Obama and Romney – the debate itself is tightly scripted, with fairly strict rules.
