While the democratic debate on CBS is still not finalized, TVNewser has learned CNN is making a push to add one more face-off. We hear CNN is working with the Indiana Debate Commission, a non-partisan group made up of the state's press associations, for a Clinton-Obama debate. Insiders tell us neither candidate has signed on, but CNN should expect to hear from one campaign as early as today.

NBC has also been trying to organize a debate in Indiana and has been working with the Indiana Democratic Party.

Indiana's primary is May 6.
